Being buggy is only one aspect, the other was the annoying change of UI that presents apps in rows of large, gawky icons instead of the previous efficient rows of title text each headed by a small icon (as say in Windows 'List' mode).
Unfortunately, this leaves me stuck on ancient version F-Droid 0.102.3.
When looking for an app this new large-icons mode is much less efficient, especially so if one's in a hurry and doesn't know what the icon represents (as one would expect with a new program).
I'd have thought the large-icon disease would have remained quarantined within the Microsoft and Apple worlds but unfortunately the contagion's now spread to Linux and even infected the F-Droid app on Android. It ought to be resisted on the grounds that there are so many new icons about that their once great benefit has been deprecated (text again conveying a deeper understanding).
I've no objection to those who find large icons an acceptable work framework but developers shouldn't change UIs just on a whim. If they so desire a change let them provide it as an option—i.e. a UI revamp should allow users to select the old one as an option (we've all seen this UI nonsense before with MS Windows, the F-Droid app is about the last place I'd have expected to get infected).
