FAQ

Undo often? By default, HTML-Kit clears undo information after saving the file. If you would like to be able to undo changes even after saving a file (as long as the file is still open), you can enable the "Edit | Preferences | Save | Allow undo after save" option. Note that more memory is required to keep undo information for longer periods of time. If you tend to keep large files or several smaller files open for long periods of time, it might be more beneficial to keep this option disabled in order to save memory.
