Is your feature request related to a problem? Please describe.
When I select multiple files and want to delete them, the menu always stays at the top of the interface. I have to scroll back to the top to perform the action.

Describe the solution you'd like
I would like the action menu to be designed as a floating menu, allowing me to efficiently perform the desired actions no matter where I am on the page.

Describe alternatives you've considered
No specific alternatives considered; the floating menu seems like the most efficient solution.

Additional context
This feature would greatly enhance the user experience by making actions quicker and more accessible when working with multiple items.
