Highlights on CotEditor 3.3
Handle documents on launch in more intelligent way
We improved various behaviors regarding document handling on launch for letting you start working with your documents more and more right away.
Sort lines as you desire
New “Sort by pattern” enables you to sort selected lines by specific column or fully freely using the regular expression. Of course, through a neat user interface.
iCloud document (finally)
We know it's kind of too late, but CotEditor now supports the iCloud document, so that CotEditor has a own space on iCloud, moves files to there easier, and can resolve a file modification conflict visually.
