Shortcuts are great, but you can't create your own and dismissed/deleted Shortcuts are automatically filled in based on your browsing history. This can gunk up the Shortcuts list pretty quick if you're not paying attention and pinning sites you want to keep as they appear.
Lets say you have two rows. You've pinned 10 Shortcuts as they're sites you frequent. There is no way to manually add a Shortcut, so the other 6 Shortcuts are then random websites pulled out of your History. And I mean random - like an Amazon page for a coffee maker or some site you'll never visit again that clicked over to from another page.
The options with unpinned Shortcuts are Dismiss or Delete From History. But if you choose either, the removed Shortcut is immediately replaced with another, random site*.
It would be cool to have the following options:
*Yes, there is a bit of a workaround: If you delete your History you can then go and dismiss all the random, auto created Shortcuts but you still can't create your own and the empty spots start auto populating again after a few site visits.
