When clicking the + button to add a new release, it only gives you a very limited number of inputs to create the item, which don't appear to be customisable.
When creating a release card, you can determine which items are visible and layout, so that it's clear what's important and necessary for your reporting.
I want to be able to customise the popup for new releases/activities, etc in the same way so that when I create a new item I have the same flexibility as if I was uploading via csv (ie: can pick and choose what gets populated).
Thanks for sharing this idea! I believe what you're asking for is possible.
From a release drawer/details view, click ...
and select "Edit custom layout". If your workspace doesn't yet have a custom layout for releases, you will see a "Create new custom layout" option.
From the custom layout builder, you can customize the fields on two different views -- release view and create release (pop-up). Select "Create release (pop-up)" to add the fields you would like displayed. You can even set certain fields to be required.
Any field you add will be displayed in the "Create release" pop-up.
I'll resolve this idea for now, but please let me know if this is not quite what you meant.
