You're looking for InnerSpace (from
Lavishsoft, a company owned by the original creator of MQ2). This has a subscription fee though, as opposed to MacroQuest 2 - I don't know how much it is monthly at the moment since I can't remember my login on the top of my head, but it's a few bucks per month or so. When you have InnerSpace installed, you need
ISXEQ2 which is an extension to the foundation built in InnerSpace, which is available on one single payment form - $12 for 3 months.
I've used IS & ISXEQ2 myself back when I still played EQ2 and it worked great at the time! As IS/ISXEQ2 has an own SVN that will update it all automatically if you allow it, there's no compiling etc involved as in MQ2, just press the icon and it'll update everything (including plugins and scripts if need be).
Even if the programs and plugins involved has to be paid for, it's largely by the same authors as MQ2 and the closest you will get in EQ2.
Edit: On the other hand, I couldn't tell if it works for EQ2 Extended, but I see no reason why it shouldn't.
