There should be "Show all" option.

Yes but there used to be a 'slide' option to go between the two pages of shortcuts from the 'home' screen. Not very good now is it? Another backward step. Also, used to allow far more shortcuts than the sixteen we have now. Disappointed 😞

They've removed it, because discoverability of this 'slide' option was poor. It's still 16 under "Show all" though.

Slide option was easily discovered by me. I can't add more than 16 shortcuts. Please bring back the slide option and allow more than sixteen shortcuts.

I also am voting for paging and larger pool of shortcuts
