I have a lot of complaints about this too, but namely lack of seamless updates is baffling to me.

Luckily I found Droid-ify and solves both those problems. Also has the common repos frequently added, like IzzyOnDroid, easily pre-available to enabled in the settings.

This definitely replaced the archaeic fdroid client for me, they desperately need an overhaul as it's a terrible first impression.
