When I enter in something into the favorites or ignored input i get something that looks like this:
When I press Enter after this point, the system pulls up the dropdown, chooses the first highlighted and then adds a space for me to add another tag. Note that the suggestions ignore the trailing dash..
So if I then type a
* for a wildcard after I typed
jquery- (so I now have
jquery-*), this is also ignored by the autocompletion, leaving the previous suggestions intact. If I then press Enter it will again insert the selected suggestion from the dropdown and append a space.
I suggest that when a user types a
* the autocomplete should not match anything, and when the user presses Enter it should just add a space next to the text that was typed (
jquery-* my example) and allow for another tag to be entered.
