Carry a flavour of F-Droid with the previous UI but current codebase
Please carry a flavour of the F-Droid client äpp that’s built from the current codebase (and so will have all relevant security upgrades etc.) but offers the old UI/UX.
Choices are different .apk (so one could install an “F-Droid Legacy UI” äpp) or a setting in the äpp preferences.
This is really important because the new UI scares away users, even experienced ones (I’ve seen this) based on subjective/perceived issues, besides the objective ones (e.g. looks suboptimal on small screens/old devices).
