I quite like the button free approach that I see. Wouldn’t mind keeping it, and be forced to just keep typing tags.
IMG tags, and paste feature, now working wonderfully… like it. Everything sizes nicely on all devices.
Editing now plays nicely… also good!
Would like a working preview, and a bigger font in the textarea… or to remember to put my specs on when posting.
Everything else has been mentioned by others, so I assume are on the way later.
