More scale settings + Add a screen scale bar on top of a screen (below the screen brightness bar and volume bar)
Among the many apps which I've tested on Pinephone with PostmarketOS + Phosh installed, a common problem is that an app's UI is not adapted for a small screen and many UI elements are not accessible. I reported many of these problems to the app repositories, however it will take time to solve them - and that's if an app developer cares enough to help.
Currently - at Phosh 0.15 - the only way to change a screen scale is to go to Settings --> Displays, and there are only five settings: 100% , 125% , 150% , 175% , 200%. Need to be able to go below 100% and more granularity: i.e.
50% 60% 70% 80% 90% 100% 110% 120% 130% 140% 150% 160% 170% 180% 190% 200%
or at least
60% 80% 100% 120% 140% 160% 180% 200%
+++ Because for different apps the different scales are convenient, it would really help if there would be a quick way to adjust a screen scale by a special bar on top of a screen, next to the screen brightness bar and volume bar.
