I’ve added a new tab style called slanted and also added some more variations on the two existing square and rounded styles.
Square
There are now 6 variants on the square style. Here are the small, medium and large spacing variations with all the tabs the same size.



The next three also have small, medium and large spacing but this time the selected tab is a little bigger than the unselected ones.



Rounded
Just like the square style there are 6 variants, with the same small, medium and large spacing options combined with either equal sized tabs or the selected tab being larger.
Here is the rounded style with medium spacing where the selected tab is larger than the unselected tabs.

Slanted
Our new style does not have variants that alter the spacing between tab instances. But you can specify if you want the slant on the near, far or both edges.



Just like the Square and Rounded styles you can also specify if the selected tab should be slightly larger than the unselected tabs.
Next Up..
I have not forgotten the requests from the last post. Next I will have a look at OneNote and see if I can copy the style of border they are using. Plus a look at trying to create a smooth curving style.
