You can use neostore or droid-ify for material fdroid

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.

You can get Droidify and it provides a more pleasant visual experience.

I personally like it. However there are alternative apps

The ui seems ok, but the search is so ridiculously bad I'd don't know how they did it.

God I hope not

I sure hope not. No no no. Material you is ugly, and in 99% of apps not an option, but a forced changed. No need for that. It looks good enough for an app store.
