Sometimes, when working with databases providing more than just a couple cubes or entities, finding the cube or entity you're looking for in the drop-down lists can be pretty cumbersome when no search function is available. Consider this example from the action library for calling a procedure
If, however, developers would like to look up the cube for an alignment or extraction, or an entity that shall be extracted, they'll have to scroll the whole list to find the desired entry, like in this example
My idea would be to enhance those actions with a search function similar to the procedure call - that would make life much easier.
