Windows11 (22H2), display resolution 3840x2160, dpi scale 150%
App UI - viewer
appearance of overlay tools (background color, corners, borders) looks inconsistent

Suggestion
bring some consistency to Viewer overlay tools (see nomacs ui)
- Info
- change defaults
- text color - white
- background - black, opacity - 50% (transparent black looks much better than white)
- change defaults
- Pan tool
- visible area selection
- change dash line to solid
you may have dashed image selection and dashed rectangle in pan tool at the same time which does not look nice
- make background area (around zoomed area) darker (like in acdsee)
- border
- add settings to modify width (to remove it completely) and maybe corner radius (imho not necessary)
- position
- add functionality to reposition to other corners
- visible area selection
- Histogram
- border
- add settings to modify width (to remove it completely) and corner radius (to remove it completely)
- position
- change default to top-right corner
- border
- Playbar (in Fullscreen)
current play buttons looks outdated (win7 style?)
- make them flat and simple
Example
- nomacs
all overlays enabled
