Look and feel is not configurable

[bigfoot547]

Make a property or something that allows configuration of the look-and-feel of the launcher

Somewhat related to this I would say is to add support for high DPI screens/display scaling as my 14" 1080p screen makes it uncomfortable to read text.

[bigfoot547]

There's unfortunately not a way to do that, as swing was not designed with high DPI displays in mind. Try to run the launcher in compatibility mode or use a JVM that does not report itself as "DPI-aware" despite not being so.

Edit: you could also try passing the JVM option -Dsun.java2d.uiScale=2.5.

Using the command(s) java or javaw on windows, passing that JVM option, then specifying the jarfile seems to have no effect on the UI scaling unfortunately.
(Small update also is that this doesn't affect my main Arch machine, but does on my Win10 LTSC laptop, so probably a Windows issue/Windows JRE idk for sure…)

just had DPI issues of my own on a 4k monitor. The issues are upstream of the launcher though, so really you should use windows's compatibility settings on javaw.exe to have it ignore the "dpi-aware" status which is erroneously set for a lot of JREs.
