Moncai Compare Moncai

EquipCompare. Many have used it, many loved it. Then, Blizzard added it's own implementation. However, this requires you to hold the shift key every time. Not anymore! MoncaiCompare is a lightweight addon with zero overhead to bring you the comfort of the original EquipCompare using as much as Blizzard's own code as possible. Automatically showing comparison tool tips in the bank, at the auction, in your bags, when looking at quest rewards and when clicking item links.

StarTip Starlon

Huge appreciation goes out to ckknight for a ton of code. If you remember CowTip, StarTip is similar. And many tributes go out to the many library authors whom have written the numerous libraries StarTip's script environment is built upon. StarTip provides an environment for your scripts.. This environment provides functions such as UnitName, UnitLevel, etc... If it's not available, try _G. Also, much of LuaTexts by ckknight is included. Some of it is untested currently.

ToolTipTabs Ali1331

ToolTipTabs allows you to open many different chat links at any one time. Each time you open a new link it is added to the tooltip and receives it's own tab on the left hand side. You can switch between these with left mouse button. Not only does it allow multiple tabs to be open, but also multiple tooltips. So, you can have 2 tooltips open, maybe one with 3 tabs and the other with 6.
