For sure, it's on my todo list!
There's a lot involved in Achievements so I've been putting it off.

For example: You have to detect if specific criteria have been met, then send that over via the Steam API which will work differently depending on different achievements, and make cool achievement icons that make sense for every achievement.

It's not super straightforward sadly! But I'll get to it soon enough. :)

Sweeet! I really look forward to this being added, its one of the biggest things that keeps me replaying games! Thanks for the feedback!
