Give the option for a multi-select picklist to be formatted as a dropdown
In old forms, multi-select picklists being synced over from Salesforce appeared as a dropdown (if they had a long list of options), which users could multi-select by using SHIFT+click. In the new forms tool, multi-select picklists are displayed as a series of check boxes, no matter how many options are given. This makes very messy, long lists, and make those fields virtually unusable in any sort of marketing form. Please either revert to formatting multi-select picklists with lots of options as a multi-select dropdown, or make the multi-select dropdown an option for displaying that type of field.
