Toolbars are difficult to use on hi res monitors, as they become way too small. The provided keyboard shortcuts are appreciated and essential, but larger toolbars are also needed, for functions not accessible via keyboard.
We are working on rewriting Greenshot completely, first the "core" and the editor has to wait a bit longer, than we will check what we can do about such "annoyances".
This is really a highly desired feature.
If I may notice, as I came here to report the same issue, after reading through the board I’ve noticed that in
there’s a mention of Preferences > General > Icon Size settings. When changed from 16 to 32 the size is rather acceptable on my hi-res screen.
I believe this one should be marked as resolved.
