Absolutely love this feature, and one ive not seen anywhere else.

BUT

It's really really buggy. The screen handling is terrible, can't click to a position in a post to edit, you have to use your cursor keys. When typing sometime the text appears at a completely different place in the post. Sometimes the publish via mobile button doesn't work, can't add more than 1 image via Instagram because of this. 

Are these issues known? ( i'm aware it's BETA) . This will be an awesome feature , when it works properly
