[Feature Request] make top of alias-table sticky (UI-improvement)

[knstntnb]

Hi,
as I really like the new design of the admin-interface, I recently got "stuck" in my personal workflow.

From time to time, I check and validate my aliases I have and delete unused old ones. Usually I will do this in the "show 100 items" view, but I find it "unhandy" to checkmark those aliases and then scroll back to the top to choose the action-item (e.g., delete).

My suggestion would be to make that action-bar sticky while scrolling further down, so that I can checkmark an item and directly choose the action for that.
If you don't find that useful, or it is way too complicated, then just close this request 😊
