Unless you're taking requests to make mods for people (which, judging by your deathrun requests, you can't), I don't think we need a "mod ideas" thread.
First because lots of people already made threads like this. For example:
viewtopic.php?f=13&t=3011
Second, because most modders are busy with either their own mods (Alesan, for example) or busy with other projects.
Third, it's easy to just go "I'd love this, this and this on Mari0". I did that myself on
my very first post, but as you can see there, people are not willing to work for other people that just dump "ideas". The best chance you have to getting what you want is by doing what I did: doing it yourself. It's also a great way of learning programming and game design in general.
Last, but not least: is this a "anyone can have ideas" thread or is it targeted at some specific people? I'm betting it's the first, but I don't see anyone willing to put the time and effort to make a mod, especially since these mod requests are usually very complicated to implement. Modding is not as easy as you might think.
tl;dr Nobody in Stabyourself is willing to take mod requests. Maybe specific features requests could work, Alesan and I do this all the time, but whole mods from requests, no.
