If you think the first level of your TagExplore browser is too crowded (because it displays every one of your tags), and not all of them are suitable for being in the first level. Then you can hide some of them.
To do so, simply open the database preferences panel (the preference item labeled with your database’ name), and scroll to the bottom. Check the “Hide selected tags” option, and get rid of unwanted tags by dragging it from the left list to the right.
Dragging tags to the right list doesn’t mean you’re deleting them — instead, they are just not going to be displayed in the root (first) level of your TagExplore browser.
