TL;DR
You can consider this mod in maintenance mode. No new features anytime soon.
Long version
That's a good question... I've been asking myself "Should I continue working on this mod ?" for a few months now. And sadly, the reasonable (& probable) answer will have to be "no".
From a user perspective, I can agree that this Mod is extremely barebone. And to get "only" this far, it took 36,000+ lines of Lua, and quite a few headaches iterating/improving upon algorithms from research articles. Only this far took pretty much a year of work full time. Technically, I'm sure Dana is already in the top 10 most complex mod on this portal. This was quite a hard ride, but certainly a ride I'm proud of :-)
These last few months I did work on an experimental branch, which have a couple minor new features. It cost 4,000 lines of code... Too slow and demotivating. Part of it is because I set extremely high standards in quality (probably way too high just for a mod). But the main issue is that I have to use Lua for a Factorio mod. This language is inappropriate for large, complex, performance-critical projects, which is what Dana is. I'm not productive enough. I looked really hard into libraries/tools to become more productive with Lua, but it never payed back. Lua is quite a barren language where if you need a wheel, you have to invent it. Even if the wheel has been available on any other high level language for decades.
