We got an app icon!

In this release, I managed to add the app icon and logo for this project.
To easily manage multiple printers, I added a "Manager Printer" section to the navbar.
Additionally, I fixed many styling things for the dark theme and some text overflowing issues.

Currently planing the PlayStore release.

If the app does not start after upgrading, please completely remove any data/clear cache or deinstall+install it again.

Cheers.
