The tab name should be moved a little to the left to allow for slightly longer names. The tab color thickness should be customizable, it's a bit too think as-is.

PS: To export/import your tabs, go to the help menu via the "?" next to the "Subscriptions" header in the sidebar. Import/Export buttons are at the top left and right.
