Hi Paul,
Apologies as I accidentally clicked 'Accept Answer' to your reply when editing my most recent reply.
Regarding #1, that would be great if you could incorporate something that would take the user back to the page when finished editing via the front-end like version 3 does.
Regarding #2, I have a first load screen ( http://dryfivedev.com/jce-first-load.jpg ) shot and a pinned-left image to demostrate ( http://dryfivedev.com/jce-demo-pinned-left.jpg ) ... currently the user needs to reposition the JCE window to gain a full view. Maybe the option of it pinning top left (or centered on the screen) would be a better option to save the user a few clicks and drags for those that JCE editor frequently. Even better, have the option for the JCE window to launch once the user clicks inside the Text Addon.
I've also noticed another issue with PB 4 Text Add On where I can't edit using just the standard text block that loads ... I need to launch JCE to make any change. Could be confusing for users that wanted to make a quick change. Here's a video to demonstrate: http://dryfivedev.com/text-addon-issue.mov
You'll notice in the video that it's impossible to place the cursor after the last line of text to add additional text. Instead the text gets added to the beginning of the text block. It's also impossible to highlight any portion of the text ... when trying, the entire block gets highlighted.
Regards.
