Actually there are two ways of adding maps to the new HSFX install: one is by adding modded maps to Rootfolder\files\maps but as I want to leave everything untouched from HSFX (just to be sure I don't mess things up 'cause I am not yet familiar with the HSFX structure) I do it the way as I was used to do it:

-In the rootfolder create a Mods folder and in that one a Mapmods folder so it looks like: Rootfolder\MODS\MAPMODS .
-In here put the maps you want and don't forget to add the _Tex folder as your added maps might have textures that are not included in HSFX.
-The next step is the all.ini: go to Rootfolder\Files\Maps\all.ini and make a copy of the HSFX all.ini and drop it in your MAPMODS folder and add the extra lines of the new maps.

Now your new maps should show up!

I added some other mods in the MODS folder and they work, they overwrite the HSFX ones.
As far as I know it hasn't still been sorted out for the soundmod. That's the only thing from HSFX I'm not satisfied about.

Yep, I prefer to put it all in my Mods folder, then it can easily be disabled for online play if neccessary
