I know the
Quark-editor has a great fast-loading texture browser and it can handle many quake-based games. Unfortunately mohaa isn't fully supported yet. I know most people swear by mohradiant, but I've used quark for about 4 years and it has some great features (I'm now using mohradiant btw). For instance you can actually compile from within quark without crashing or using a seperate batchfile like Mbuilder. The interface is very user friendly with its explorer-like worldspawn property window.
Although it's a very stable editor in itself I wouldn't advice people to use it with mohaa. The texture browser is great but you'd rather extract the textures from the pak2.pk3 and use a viewer-tool to browse through the groups. (try tools like
thumbplus or
xnview.) However, the disadvantage of using viewer-tools is you'd still have to manually type the texture's name and pathname in radiant to load it after you've found one you'd like to use:/.
[anyways, here's a shot of quark's tex browser]
