Since I released not even a week ago - I've get about a dozen requests a day to port Fritz to about 8 diff ET mods so far. Its gotten so bad, I've added a part in the FAQ about it.
I can't - I just don't have the time to recreate every single mod out there, and most mods are not open source, so its not a situtation where I can just grab the source, and dump it into the Fritz code (EX: ETPro is not open source, while I could re-create their features, its taken them years to get where they are now - I'd rather work on the bot).
The only mod I know of that is open source, is ETPub. So, odds are MUCH better that if there is an ETPub feature you really like, its open source, and the ETPub team is cool about sharing, that you'll see it in Fritz.
Next version, I will expand some of the general game features - but my main focus will always be the AI.
BTW: If you have a feature that you really want, and can point me to source code, or supply the code yourself, I'll use it.
