Viewer - Grid Settings
UI is outdated and not in line with other tools
Suggestion
Few things that could be changed:
a) rework 'Defined grids' section into 'Presets' to keep UI consistent across app.
b) remove this small old color palette and show standard full size color picker instead.
Example
- Photoshop
- Gimp
