I think that makes sense (probably for all TUI subcommands), however in this case I think the workflow should be:

• If the user is actively typing in a filter esc sets the filter (as it works currently)
• If a filter is set esc clears the filter (as it works currently)
• If no filter is set esc exits the TUI
