While reviewing MDL-67786 I visited a bunch of Admin -> Plugins -> [Plugin type] -> Manage pages and found them pretty inconsistent.

• The basic (common) columns (name, enable/disable, settings and uninstall) are placed differently.
• Some plugins show number of instances/uses and version, others do not.
• There are other options, like up/down, testing, protect...) that aren't in all plugin types, but, when present... they should be shown consistently.
• ...

So basically this is about to review all those pages, decide a number of rules and apply them to all pages, towards - visual - consistency.
