Consistency is good. But I find the update flow to be annoying. Touch 'updates' tab, doesn't show you the updates until you pull down (with no affordance), update are summarised but not listed in the big space for updates to be listed, "update all" then doesn't update all but instead lists the updates in that big space, tap "update" on each item listed, you get a popup asking if you want to update it (because the two previous choices of "update", after already going to the update tab, might have been a mistake?).

I appreciate it, but it's a weird flow. I'd expect touch "update" tab would run the "check for updates" without needing the pull down (maybe set a cache-time in settings); "update all" would do all the updates without any other taps (or with at most one [per app]).

Not being able to update multiple at once is an android security thing isn't it?

Maybe, Google Play can do "all updates", but they maybe do shenanigans.

Interesting points, I agree the Updates tab could do better there. Update All is implemented if you have F-Droid Privileged Extension installed, it could also be implemented when it is directly installed, if someone wants to contribute there.
