With reference to this thread: Created folders to organise my html files, but PG has added a unique 'styles.css' to each one?!
I feel that PG just creating additional files without warning or asking is unhelpful, especially when there is no information presented to the user to inform them that this is happening.
I would strongly suggest that you ask the user what they want and only provide that, and in addition have a toggle-able setting to stop auto creating files with no warning.
As suggested in the OG Thread, it would be clever and useful if PG asked if you wanted these files (it would create them on folder creation) or if you wanted PG to update the links to the files (style.css et al) so that when you moved the html pages into folders, it would update the links.
Or an option to do nothing.
It should also be possible to drag/drop your html files in the PROJECT panel into newly created folders, and these relinking or file creation messages should be presented at this point.
The most confusing part was I had to do the drag/drop in Finder and when I re-opened pinegrow these new .css files were created without any warning and it just confused the user.
