Works great with WP 3.9, seems simple and light weight and gives me just the right set up to write in both languages I need.
But, there are a lot of improvements that could've been made already, and the lack of updates worries me, because it does seem like the developers have forgotten about Stella.
I wish they could make it easier for developers and people who are not quite there to add custom content that we need translated.
Possibly, expand the default translations to Author Bio (since author boxes are a must-have these days) would be great.
Just minor tweaks, because I don't ever want it to loose the light weight and simple feel Stella has.
It's just a little stuck in the past right now. The last update is from 2012...
I hope they do something to it soon. It's a dream plugin for people with multilingual sites/blogs.
