Exciting to watch the work on the editor progress @steemchiller! Fortunately, I've been using HTML almost since it was introduced, so that's not so much of an issue... as is keeping up with tags/formats that become deprecated.
One of the things I always appreciated about the Blogger platform editor was the ease of image handling: Upload an image of pretty much any size format, but then there is a choice of "small, medium, large, X-large, Original size" followed my a second choice of "center, left justify, right justify" with the side justifications automatically resulting in text wrap. Captions were a separate input box "tied" to the image.
I imagine that's a coding nightmare, when sizes have to be parsed for the screens of a vast range of mobile devices, laptops and desktop units.
Anyway, keep up the great work!
