Describe the feature you want to add

If a request gets single clicked in the navigation pane, it would be great to have it opened in some sort of pinned/temp/preview tab.

Single clicking the next request would open that request in that pinned/temp/preview tab.

Double clicking of a request would open it in a "regular" tab.

This would help in navigating through collections and declutter a lot.

It could be optional on application, maybe even on collection level
