Please revert Resources/icon-edit.png
Making the picture executable is not needed.

@devendrn You can decide about this, I'm more towards rejecting this without being disabled by default using launcher settings and a checkbox in the General Page.

The qt6 branch as used in flatpak/AUR is the development branch.

I made it, non-executable, not executable.
Edit: oh wait it mustve been a typo

misread

[ChristopherHX]

Making unrelated changes to pictures could cause a merge conflict with the qt6 branch as well.

I dismissed the requested changes state now

[devendrn]

@Hzqkii Open a new PR to the qt6 branch. I will manage the rest including the toggle option to enable this. I may also change the icon, as it does not match the design style of other icons.

I'm closing this PR as I don't want these changes in ng branch.
