In the current version of Krita, the Overview Dock always show the full image, which is the desired behavior in most cases.
However, sometimes we’d like to focus on a specific region of the image. For example, if you’re working on a comic page, you might like to focus on a single panel. But you might be doing the lineart for it and your main canvas is super zoomed in (because you only have a small budget tablet… we all have this experience right?)
In this case it’d be better if the Overview Dock can show the single panel only.
My suggestion is to have two buttons on the Overview Dock:
Crop: when pressed you can drag a rectangle on the main canvas. Everything not in this rectangle will be cropped out in Overview Dock, and Overview Dock will zoom in / out so the cropped region fills the Dock’s size.
Reset: reset cropped region so the Overview Dock is showing the whole image again.
I really want this feature too. It’s not just for comics, even when you draw a character, especially on Android, you might want to have an Overview for the whole face when you detail a mouth etc. In my perspective, the cropped part should be shown without any canvas rotation.
I feel like instead of making a rectangle on the canvas, it should instead just let you zoom in and pan inside the Overview docker like it does now but instead of changing the canvas zoom and pan, it should set that crop region. There should be some kind of a setting next to it to make it. It should be however done in a way that you can do it with just a pen. Maybe buttons to zoom in/out, then.
I had that ‘crop’ button idea because I kinda like the current behavior where it zooms automatically according to the dock’s size. If one uses the dock ‘docked’ instead of ‘float’ like I do it might be less useful I guess.
Which is… useful, but a little weird. We already have many ways to flip the canvas (in the RMB palette, with a shortcut, etc). What we lack is the ability to flip the Overview while keeping the canvas as-is.
