About this fork

This fork attempts to revive lightly with a different approach from boehs, with the assumption that Luwx won't ever resume his project.

This means that this fork allows real changes, and not just maintainence.

Lightly

The to-do list

[x] Make a new readme
[x] Make install work on plasma 6
[ ] Find ~~some~~ more people that can help with this project
[ ] Build some community
[ ] Make some meaningful commits
[ ] Expand to-do list

My plans for changes at the moment -- They are in progress, I'm just really slow

[x] Redesign the tabbar
- [ ] Fix the issues I caused with it
- [x] Align it a little better, ~~now it's slightly too left,~~ it needs slightly larger margins for ~~both sides~~ the right side
- [x] You can now set the old tabbar back if you dont like the new one in the settings
[ ] Make the buttons sligthly larger
- [x] The standard push button is now slightly larger
- [x] Spinboxes and comboboxes
- [x] Now the size of the buttons is adjustable by the user in the settings
[x] Change the defaults to fit the normal use-cases better
[x] Add my own colorscheme to it
[ ] Use klassy for window decorations (I don't know how to use make / cmake, so it'll take a while)
[ ] Make installation in all major distros easy
- [x] Can be built on most distros that support plasma 6
[ ] Rename the project to something like „Darkly” to reflect the changes, and for it to be installable alongside the other lightly
[ ] Maintain the project

Known issues & solutions

Blurred icon rendering on Wayland with fractional scaling

As referenced in https://github.com/Bali10050/Lightly/issues/14

On Wayland when scaling is set to >100% some icons appear blurred.

The fix for now until QT is updated is to add QT_SCALE_FACTOR_ROUNDING_POLICY=RoundPreferFloor into the file /etc/environment

Restart to apply the changes.
