Sehr gern. Danke fürs Feedback!
Well, I probably made the screenshot with the German keyboard enabled. The German keyboard is QWERTZ instead of the US QWERTY.
Yeah, a way to check for syntax errors would be pretty cool. Maybe I could create my own service for that.
Yes, I had a look at it recently. Thanks for mentioning!
A customer reported that korean characters do not work either.
I see. This could be added (along with other commands like "convert to upper-/lowercase") to the context menu that pops up when you make a selection.
I have no explanation for the fact that it seemed to be more sluggish at first.

But it's good to hear that it's better now :)
