I found this new thing a bit clumsy compared to the previous. Too much clicking, not to my tastes ;)
so i looked at support, and there seems to be helpful thread:
WYSIWYG editor thread
I asked about how to get rid of quote-pyramids while quoting post with quotes of quote, and amazingly fast got response. Thought to copy it here too if others have same problems.
It can be a bit tricky. If you want to delete an interior quote, then you can click into then click the "Table" button and choose "Delete Table". This will remove the interior table. If you want to remove a higher level quote then it can be a bit touchy. You have to just delete what you don't want.
