to only shows the maps in the current mod?

currently seems to list all maps, including in the ID1, which might not be mod compatible 

Also can the old school quake underwater effect be brought back as a "r_waterwarp 2"? 

Macs applications can't do command line parameters.
Hmm... since when ? But i believe you. macOS should have it's Unix accrediation revoked. It's a disgraceful clusterf*ck of a design mess with no regard for anything but making a buck, lock-in, and selling disposable hardware. I turned off about 4 years ago and just run Mojave on my household laptops. Now get off my lawn :)

Sounds reasonable... Currently shows all maps in id1/maps (which in my case is quite a few) mixed up with mod maps (shoved into 'extralevels').

Maybe i'll code this ? Probably easiest to do something like "maps_mod". Just had a quick look. haha, geezus our data structures are basic. 

I incorporated the following RL and NN library of mine here
https://github.com/frabbani/ML/tree/main/c/reinforce

into my own quakespasm branch here
https://github.com/frabbani/quakespasm/tree/rlearn
(it has other stuff too, but look at sv_move.c)

i also have quakec changes here

can you add all the ironwail features to QS?

The reason i ask is, today apparently i discovered, ironwail and QSS are incompatible with certain mods (was playtesting Malice DE), but I love all their missing features which I always wanted in QS 

what do you mean by "all the ironwail features"?
