In anticipation of future overhauls to front-end word processing, I wanted to raise special consideration to literature submissions. The December update to address esoteric filenames added the ability to live-edit text submissions (as replacement uploads were disabled pending an overhaul of the back-end), which is very useful, although it does suffer similar problems to comments at large where the preview does not translate into the post. (This editor also parses primarily through HTML tags, which depending on its dependencies, may not square with BK's bid to consolidate site syntax around Markdown.)
My main focus, however, is allowing for greater formatting options. DeviantArt's spaghetti code involved a lot of trial and error, but if you knew HTML you could manage a fair play of tricks; these were bulldozed by Eclipse and made it literally impossible to preserve even semi-complex formatting unless files were submitted as dedicated PDFs. I'm wondering how more comprehensive Side 7's editor can be made specifically for literature: different fonts, preserving white spaces, handling sectional links for internal tables of contents, etc. Given the site can parse .RTF and .ODT files straight-up, the quantum leap would be presenting them verbatim, in their original layouts.
The other question is whether PDF support is possible: as I surface from the latest bout of archival mirrors, the countdown's started on certain pieces that I literally cannot replicate accurately not just here, but in most online word processors.
Last and probably least, we could expand literature categories beyond the current "Non-Fiction" catch-all, though that I may spin off into a general-purpose thread.
