Upon release, English will be immediately available. But it's more convenient for me to develop in Russian.
As for the progressbars, they are for each class at the top left. Under the portrait, a thin dark red works like in the original game. And the orange one starts from the beginning with each level increase.
On the right shows the number of experience/killed.
And I changed the colors a little.
There's something else there, by the way. I wrote the lower/upper functions. Because standard lua functions normally work only with English characters. Now they work for Russian and English. For other languages, I will only do it if the mod is translated into them. To put it simply, it's just a converter of utf-8->Unicode encodings and vice versa.
