ah, thanks for the arrow button explanation. I only worked with 4 colors so far ;)
about the reordering idea, I really explained it a bit confusing. But I think you got it exactly right. Changing the map order would also change the order of appearance of the preview pictures on the right that have the maps applied. This is really what this is about. It would allow me compare output images with similar mappings / map palettes applied more easily. (One implementation idea would be via drag 'n drop, by dragging and dropping the output images.)
>> It would be great if instead of saving one big output picture, I had the option to save individual pictures for every palette in my project.
> Another great idea. I had only just recently added the ability to select between stacking the maps vertically or horizontally in the output picture. I'll work on adding a third mode for saving them a series of separate images.
That's great! :) Since your tool also supports CLI mode, I already created a little PowerShell Script that creates separate images, but having this in the UI would be more comfortable :)
> What you'd want would be paths that are relative to the project file, right?
Exactly. Maybe the user could decide if he wants relative or absolute paths. Ideally the save dialogue would have a little checkbox for this. But I don't know if that's easily possible to add. This was just a minor idea though, since editing the text file is always possible, as you said ;)
About fitting more maps in the preview area: you're right, it depends very much on zoom and the source image dimensions if this is useful. But I don't think any smart logic would be necessary to determine a layout of the preview images. I'd be happy if I was able to edit the amount of vertical preview columns manually and this would keep things simple I think :)
Thanks for considering my feedback! I'll be eager to test any updates you release :)
