Add a customizable description box for each skill

When you click on a skill, the PHB skill summary appears in the sidebar. I would love the ability to add/customize the description. For example, with a customizable description box, I could copy paste the jumping and climbing rules in that sidebar so my players can look at them at a glance, or add house rules for a particular skill. 

As a side note (it was another requested feature somewhere in this forum), it would be great to be able to customize a skill with Advantage or Disadvantage at a click of a button / toggle.
