Annotate mode: Contenteditable add, remove text, accept and reject change, accept and reject all changes, add and remove comment. for users with modify. annotate is added as revision with invisible functions and user tagged. annotate context should be exluded in search
Check user rights on virtual selects
Data collection from logs
session_close_write when possible (no write for sure, not filter to check, maybe for these use lock)
more efficient bitmap graph (rect over multiple pixel) or ad hoc rle pict
split short.txt and urls.txt
Allow for acculumate revisions (can accumulate small content appending with timestamp like a log)? must be in a separate folder like named logs
