It seems that I haven't expressed myself correctly. I meant upgrading from 3.4.7 it transfers all keys to 4.0.0 but theres nothing to do with old translations. And then theres new keys mixed with old keys.
I hope it's a bug, because theres so much unneeded key's now and ~260 pages become 690 (as I remember the fresh install had ~260 keys?!). And cant find option to delete them. Believe it's quite confusing this way.
No, it's beta 5a (from 3.4.7). Haven't tried beta 6 yet. Converter was 1.1.13 (to believe page footer). I did open a support request and got an answer that "we do not provide support for beta software". I copied your request as well but nothing.
I have a problem in Estonian language. If someone I follow likes something, everything is fine:
But when somebody quotes or mentions, then topic/image/event is uppercase (using system key):
It's ok in English but funny in Estonian. And in my case, quote and mention notifications should not use only Topic/Image/Event phrase but longer (like in first picture "a post in a topic") phrase like " you in a topic/image/event " because right now its a noun but this case I need a inessive for Estonian. In first picture I can do this, second no. %s has posted new %s in %s - this has a noun in the middle as well. Would like to see own keys for notifications, so the don't use System keys in the middle. Then I can use noun for inessive as well and won't ruin something somewhere else (using system key). Emails use noun as well - Go to this %s. In this case I would see own keys for email content so the don't use System keys etc.
