No worries, as long as its in a separate tooltip. It fixes lots of problems with the tooltip reading/reloading and especially if other addons uses the same wow-default tooltip.
Putting things in a separate tooltip avoids all that :)

Suggestion though, maybe you can open your Tooltip hmm, KC_ToolTip to others so they can use it as well? :D

Just Installed - Not Working - Seen as Dependency??
 

After reading the reviews, was excited to have a lot of mis-matched mods rolled into one, managed by one developer, so I thought I'd give it a try.

Downloaded from here, latest version, dropped in the folder, and when I look at Add On's from within WoW, the folder is seen as a dependency. Did I just miss something in the instructions (been know to happen) ? I moved a few folders in and out experimenting with no results.

Any suggestions? Thanks

Get that and you'll be fine.
