A sticky thread for useful programs?

[vonCarstein1984]

How about it?
Just a thread where every moder can put links to freeware software he found useful when modding.

notepad++
A text editor that is capable of syntaxhighlitghting and most important you can define your own programming language (so I defined one for the AoD script language)

and of course
gimp
for anything graphic related

edit: A screen to show you how an .inc File with my AoD Syntax highlighting looks like in notepad++
