@#1 Disable autosave: (very) useful workaround

@#2 Find & replace on multiple files: seems to me like a missed opportunity (and add 'raw' regex when you're at it :-)

@#3 Convert HTML entities: see #5 'plugins'

@#4 Edit multiple lines at once: (potentially) very useful and timesaving feature

@#5 Plugins: a opportunity to add custom (convert HTML entities) plugin(s) would be (very) nice
