Some of you might think of your own grand new great feature for Krita, and maybe even you know how to code, but getting into Krita codebase is difficult. Or maybe you’re bored and want to help, but don’t have much time. Or maybe you want to switch industry you’re working in and you’re learning programming in spare time.
Krita’s codebase might seem overwhelming, and frankly, it is. But we can always cut the beast into pieces and just take care of a very very little part of it. I was working recently on rating wishes - feature requests reported on bugzilla - to see how many of them are invalid, how many needs more discussion, how many are difficult, how many are not. Below it’s what I rated as “short, easy, ready”. I put a lot of items so you can choose what feels the most interesting to you 
NOTE: If you become interested in one of those items, please do contact one of the developers (or comment here/below), that way (1) we can help you, (2) there won’t be multiple people working on the same thing. Also this list is for people who already know c++ and can read code; otherwise it might be quite difficult.
Very simple
Features
- 423170 423170 – JJ: MacOS' color picker pops up instead of Krita's internal color selector (change the color selector on MacOS to be the Krita one, not MacOS OS’s one which is much more limited)
- 396454 396454 – Frames display atop each other when rendering animation as transparent .gif
-
349152 349152 – When transforming a clone layer with transform tool, create a transformation mask automatically When transforming a clone layer with transform tool, create a transformation mask automatically (similarly to how it’s done with File layer or something)[taken by @QChai, October 20] -
397172 397172 – Export size during export A separate size on export (like in animation) (will need a bit of UX design)[taken by @sacjin ]
GUI
- 410871 410871 – Reorder Touch Docker (simple!) Reorder Touch Docker
- 427834 427834 – Export reference images set by default adds "." instead of full extension (very easy)
- Specific Color Selector - color preview idea - Add color preview to Specific Color Selector docker
- 381537 381537 – Zoom fit with margins? - the idea is that you could click “Fit to height” and it would fit the height of the canvas to be a little bit smaller than the height of the available canvas area
Just simple, maybe a bit longer
Tools/features
- 377034 377034 – Save Group Layers Dimensions not Retained Save Group Layers Dimensions not Retained (a bit longer work)
- 367694 367694 – Support loading palettes saved as a CSS file Support loading palettes saved as a CSS file (longer work)
- 374726 374726 – The levels filter does not have a channel selector
- 423724 423724 – Open both files when autosave present - Improvement to dialog (this might need some more careful design behind the scenes, to ensure that the user won’t try to save both files into the same location afterwards - maybe the autosave file could have the filename
filename-autosaved.kra(it’s different from the normal autosave files so it would work?) - better to discuss with other users when you take this task). -
Animation: Add hold frames based on image sequence number - When importing animation frames, add gaps (hold frames) between frames according to the numbers in the filenames(taken by @earendil_14, March 2021) -
399058 399058 – Convert the current layer into a reference image Convert the current layer into a reference image[taken by @TomWoo ] -
393113 393113 – Crop Tool: crop image without cropping the layers data[taken by ddoran3 on bugzilla] -
340643 340643 – Grid Brush: Offset Grid Grid Brush: Offset Grid (might take a bit longer)[taken by @Reinold]
GUI
- 348922 348922 – Wishbug : Extend the color patch ( previous and current color) while color picking to other tools such as gradient tools Wishbug : Extend the color patch ( previous and current color) while color picking to other tools such as gradient tools
- 387164 387164 – Switch Colors in Popup Palette when clicking upper left color circles Switch Colors in Popup Palette when clicking upper left color circles
- 409184 409184 – Feature Request: Ability to open image sequence and animated gif directly from file menu. Feature Request: Ability to open image sequence directly from file menu. (Needs to be finished: Ability to import animation directly (!727) · Merge Requests · Graphics / Krita · GitLab)
- 406699 406699 – No suitable cursor on HDR dark pictures No suitable cursor on HDR dark pictures (requires some artistic skills
)
Scripting
- 412846 412846 – Expose ways to select/deselect nodes in the Layer docker Expose ways to select/deselect nodes in the Layer docker (longer work)
Quite Important™ Bugs
If you don’t look for fun but want to make the biggest impact with your coding, you can try to fix one of the following bugs. They are all meant to be somewhat easy to fix and shouldn’t take much time (although it’s a relative measure…). They might be a little more difficult than wishes though, since you’re not writing a new code, but fixing the old one.
- 411932 411932 – Instant preview can turn off permanently
- 412323 412323 – Still-frame of last used brush shown instead of "No Preview for this engine"
- 422750 422750 – On canvas HUD color picker (square type) or color history swatches are hard to use due to no buffer area on edges
- 423830 423830 – Horizontal and Vertical Mirror tools have initial placement problems with more than one open image
- 428140 428140 – Advanced Color Selector looks ugly in horizontal layout
- 429501 429501 – Lock the recursive button when not applicable to make it less confusing
- 389346 389346 – Split layers on Colorize Mask doesn't work properly (takes ages, cannot be canceled) while it works fast after converting the mask into a paint layer
- 430240 430240 – Krita doesn't warn when exporting layers with multiple transparency masks into .psd

) which might be helpful for you, it has all the scripts so you don’t have to do anything except for downloading correct things and then running scripts. But it’s still more difficult than on Linux.
