@Yumi I understand what you mean.
But actualy, i found lomiri is not ready to be used as a PC (no desktop...). And UT don't already have some basics computers apps (libre office, vlc, firefox, scribus, gimp...). But in fact, phosh or kde mobile are not realy better.
i made a try with kde desktop (on postmarketOS) : more customizable, but pmOS is unstable on oneplus6.
So, the quest continue ! (why not mobian + kde desktop if possible?)
