Textpattern CMS support forum
Real-view Write panel
After the rest of Treepad recently, I have investigated text-file-format alternatives for my PIM with hyperlinks. And finally settled on the choice of two apps: Qownnotes and Zim. Qownnotes enriches text by Markdown, and Zim by Wiki syntax (sorry, no Textile). I would prefer Qownnotes for tag-based content management instead of tree-structure in Zim (and Treepad), alas!
Interface of Qownnotes is dual-pane (ant third pane for TOC), with non-editable final-view on the right (optional). Rats, I should always stare at Markdown! That is not the case in Zim: I always see my fine rich-text here — markup is converted and disappear automatically, instantly after a space, comma, etc.
Why not to implement that mode in Textpattern? The default tab in Write panel would stand for editing and real-time viewing according linked CSS, as from a public front-end. Two other optional views would remain HTML and Textile markup. The highest satisfaction, especially for newbies!
By the way, such real-view editing mode is already working in English Wikipedia (Mediawiki CMS), not only in Zim.
