This is actually two ideas to the same end.
-1 Currently Workbench lists transformers sorted by name only. This means that transformers of the same type are spread out in the list, if given different names. It would be very nice if an option to sort by type-then-name was added to the list, e.g. in a shortcut menu.
-2 Currently Workbench only lists transformers in the current tab, e.g. Main. It would be beneficial to have an option to have the list include all transformers, both in the Main tab and all custom transformer tabs. E.g. if one needs to update all transformers in a workspace of a particular type (in my case it was XMLTemplater), one can easily overlook one in a custom transformer, especially when they're not sorted by type.
This should be a very low hanging fruit to implement.
