feat(app): keep library settings

[ToBinio]

This Pr makes it so the filters you set on the Library page are saved in the settings and therefore persist over page switches & app restarts

[MiraculixxT]

Please consider merging this, it will make the library window actually useful again

Going to go ahead and close this since it's very outdated, but this is absolutely something we'd be interested in adding
