This library adjusts the size and padding of the World Map Info Tab on the right side of the screen.
With the "Homestead" update another build-in tab is added. Space is getting rare.
This library is working stand-alone, but every addon author adding a new tab to the World Map Info should include the library. Even if space is enough, if your addon is the only one for you. You never know.
It works well up to 12 tabs (6 addons). Beyond that symbols getting a bit small, but should work up to 19 tabs. Once one ever have that much tabs I start thinking about a more complex modification.
Here you can see from default to Atlas, HarvestMap, WaypointIt, sidWarTools:
