A sublimetext3 plugin for automatically limiting the number of tabs open at one time in a each pane.
Panezr works by tracking each view as it is opened. When a new view is opened, and that results in tabs in the view's pane being less than the min_tab_width setting (80 pixels by default) then Panezr will close as many tabs as needed to bring the tab width over the minimum.
However, Panezr will never close scratch or unsaved tabs, so if you open a lot of those in one pane, you will still get a horrible smushed unreadable mess.
