Tabs suggestion

Tabs are awesome and all but I for one don't like it when I have so many I gain another row. It makes things a bit confusing.

So What i noticed is two specific skills that stand out and have their own tab but doesn't seem to need it. Zetsu clan skills and Curse seal.
If they both just went in Ninjutsu tab that would be nice.

I also say players should have the ability to set which tabs they want to show and which ones they don't want to show.
