[Suggestion] Proper 2D texture editor
Current Problems with BB
Not easy to make accurate color & brightness tweaking (Also the plugin can be laggy and slow) No good way to make item and GUI textures, or just plain pixel art Current sidebar 2D canvas preview too small to make accurate selecting with copy paste tool or shape tool No Checkerboard or all paint tools on UV Full view
What would be new:
New Texture editing window Bigger texture canvas/preview Layers (Would be nice in 3D too!) Custom Brushes (Both 3D & 2D) Brush Editor Brush import/export Better Color/Bright editing (Currently a plugin)
Other suggestions:
Lasso Select Selection only color editing & Painting Magic Wand Select With Tolerance Invert Selection Color/Bright Curves Stretch & Rescale selection Background references Tiling mode for making seamless textures Multiple textures on a single canvas Quickcopy canvas texture to clipboard Generate collage of your textures (Like a pack showcase) Open folders
Concept i made, popup window probably isn't the best way to implement this menu, maybe just a different mode window along with animate, paint, edit tabs could work too

With descriptions:

Well, why not just use gimp, ps or pdn?
better keybind system way more customizable no app loading times Custom Brushes could be used in 3D Overall faster to work with Textures get backup-ed to the same file as the model Easy to learn
