I've just set up my first EE3 site after having produced many sites using EE2. Aside from the learning curve of a new control panel, a feature clients used to love was the ability to 'design' their entry forms (i.e. layout, ordering, columns). I've found the ability to 'order' fields, but it seems you can no longer 'shorten' the fields to enable the page to have 2 columns?
ie. I used to have a half / half split column with 'title' on the left and then 'url title' beside it on the right. Likewise for setting 3 images I'd have 3 smaller columns for them rather than 3 single full-width 'rows'.
Am I missing something or is that no longer possible?
