The extension is good, but there are some annoying little things.
I installed the script first, and everything was better there. Then came the addon, and the author didn't even bother to write an English description.
Come on, it's literally a five-minute job. Especially since you already have it ready; just copy and paste it here.

There are a lot of clumsy localization issues, both in English and Russian, but I can probably fix those myself. Otherwise, the script is excellent.

Great extension!
