I think this was mentioned before so I was hoping to find it in 5.1.10 but no - no there
If it wasn't mentioned I am doing it now:

Modules - I can select multiple to install or enable but if I want to delete 5 modules I have to do it one by one. So lets say I want to delete 5 modules, cache is regenerated with each deletion and it takes in average 2:30 minutes - so it can take up to 15 min to delete these 5 modules and store is inaccessible during this time.
Not possible to delete in bulk?
