Whenever I go to the finder from another app (using reveal in finder, for instance), it always creates a new tab. This happens a lot throughout the day. That means I always have to manage and close a ever growing number of tabs that I don’t need. Could it be that it uses the latest open tab instead, and only create a new tab when you explicitly do so (cmd-n) or when there are no tabs open?
When I have visor turned on, but don’t have tabs open, clicking on the finder icon creates a new floating window, but doesn’t open a new tab in the visor. If I have visor turned on, it should always use the visor.
Totalfinder 1.7.10 (downgraded because of folders on top performance isues in 1.7.12)
