Unfortunately, you still got it wrong - at least partly...
- No add-on for ASC with regard to writing posts - BUT...
- I do use an add-on called "Stylish" to invoke a custom Cascading Style Sheet (CSS) that makes viewing the forums and threads more "desktop friendly" - see:
Regarding your misunderstanding:
- ASC runs on a heavily customized version of Jivesoftware - I call it AppleJiveWare - there is a real 'department' called the Apple Jive Team that hires Jivesoftware Custom Coders
- TinyMCE is the Rich Text Editor implemented as a "module" or "Add-on" TO Jivesoftware in all its versions - and thus, AppleJiveWare - I know of no major modifications to it.
I do use a Mac. Firefox is my browser of choice. I do NOT experience the DDouble CCap anomaly that iPad users do. I DO see FONTsize anomalies sporadically.
For everyone, regardless of platform, the FONTsize 'switcheroo' happens in the "limbo" between the [Reply] button and the display of the result in the thread.
AlohaBob uses an iPad EXCLUSIVELY. Any issue you have with iPad & ASC = he is THE MAN
To recap... Everyone has issues of some sort. iPad has its very own glitch with DDouble CCaps on the FIRST Paragraph that can be defeated in any one of several ways that AlohaBob has posted earlier in response to my initial tip of typing a SPACE first, then proceeding normally. There is no real reason to mess with a point size difference - more trouble than it is worth.
You're welcome.
