Not that anyone here is complaining about not having looked for or wanted the following. I know that, and this post is only intended to provide a way of bridging the waiting time for the feature request expressed here, because it only covers most of it and not all of it.
And since this is a plugin, it will not be available for those using Android, and therefore it fulfills not the request as it is made here.
See it as a workaround for the waiting time until your request is accepted and implemented, if it is implemented. Also, only PC and Mac users can use Buli Notes, Android users are unfortunately excluded. Therefore, implementing the feature request would be the preferred option, as it would allow all users to enjoy the feature.
Buli Notes allows storing the brush presets and any kind of note, be it via the editor or handwritten. And in principle you can also store any used color, so the palette you used, via this plugin, you just have to put down one dab with the currently selected color on the handwriting notes area to build up your palette used so far, or you simply note the name of the used palette so you can call it the next time you open a picture.
These Buli Notes are saved into the KRA, so into your files, and you have them everywhere at hand where you use your files (if it is not an Android device (by the way, I’m not sure about the situation on ChromeOS, and if you can install plugins to it, so it may be that you are unable to use your Buli Notes there)).
Here you can see and read a little bit about its capabilities:
The full information about the plugin is found in the Buli Notes topic.
