Just tried 6.6.0. You have indeed added an ability to edit the item directly in the browser, but although that looks useful, there should still be an option to open the full editor.
So in the browser when you view an entry, which shows as a dialog box, there is now a pencil icon which makes the fields in that dialog box editable. The first time I tried this I thought, I really should make this entry a Favorite. So I hit edit. There I can edit the fields but there is no Favorite star I can click. If I could just launch the full editor, I would have that option. The full editor would also be useful sometimes as the dialog box is rather small.
So what you have added is great for some edits. Just add another button to open the full editor. I would suggest that when I click the pencil in the dialog to go into edit mode, beside the word Save, add another pencil or similar to switch from dialog editing to the full editor.
