+PROBLEM SOLUTION PROVIDED:
+Aiogram handlers remember language on the start and there's no chance of changing it in handler's runtime.
+So, here's a little hack in `change_language handler`
+
+# Cheatsheet to create/update locales:
+## Generating new:
+1. `pybabel extract -k __ --input-dirs=. -o locales/messages.pot`
+2. `pybabel init -i locales/messages.pot -d locales -D messages -l <en ru uk>`
+3. Open `locales/{language}/LC_MESSAGES/messages.po` and Translate msgs
+4. `pybabel compile -d locales -D messages`
+
+## Updating:
+1. `pybabel extract -k __ --input-dirs=. -o locales/messages.pot`
+2. `pybabel update -d locales -D messages -i locales/messages.pot`
+3. Open `locales/{language}/LC_MESSAGES/messages.po` and Translate msgs
+4. `pybabel compile -d locales -D messages`
