The borders are also a status indicator, its suppoused to be Green = ok, Gray = dev mode, Blue = update is avalible, Red = missing depedencies. But im yet to find a proper way to do that last part, if i dont end up implementing the red border i will replace green with a black border for as green would have no purpose.
Regarding mod and dev mode, i havent planned anything about it yet, and the reason is simple, i dont know anything about how it works when uploading a mod, log in to nebula, etc. So im going to focus first on everything is that is play only, dev mode will be the icing on the cake.
Buuut one thing for sure, the whole folder structure may be changed, right now im following how Knossos does stuff as this is intended to be a drop-in replacement, but in the future i may have a new folder structure that gets rid of the root pack concept as a whole, intended for clean installs. As the root packs, at least to me, makes little sense and just complicates things or make them more confusing.
I do agree about the arrows, but for a diferent reason, like going to mod settings, you probably want to go to play after doing that by staying it justs adds an additional button to click.
Mod details is very limited right now, but here ive been actually being limited by the UI framework, it dosent even have a rich text box control yet.
