FEAT: Preview mode for the top bar tab like vscode

[stunited-thien]

Is your feature request related to a problem? Please describe.
I have a big list of collections from old projects that I need to decide which one to keep for new migrated projects. To do that I need to open them one by one collection to see which one refers to or needs to be changed column value. So I ended up with a long scrollbar top bar that was hard to navigate.

Describe the solution you'd like
I want the new collection tab at the top bar to act like vscode tab in preview mode. By doing so, there would be no new tab spawned if I open a quick one just to check and pass by
