I'll reach out to you directly about the buggy behaviors so we can get that into the support queue.
Beyond that, could you share some additional details on how we can continue to improve the WYSIWYG control? What functions or features would you like to see added or improved?
An additional WYSIWYG bug is that often when the content is filled out in a WYSIWYG control and you reload the page, the content "appears" to have disappeared. Once you click on the control, all the content magically reappears.
I am not 100% sure if this is a good idea or not, but when pasting in content that has italicized or bolded content, the deprecated <i> and <b> tags are used/retained. Would it make sense to convert them to <em> and <strong> tags?
Forcing aspect ratios\image sizes into the image tag is also a huge headache in the age of responsive images. Being able to add a class upon image insertion, not aspect ratio would be of huge benefit to our users as now they have to go into the HTML view and add class="img-responsive" . Some have a little HTML savvy, but others expect it to be as simple as MS Word.
