Reports are a great way to visualize data in the way you'd like: filtered, grouped, summarized, and sorted.
The problem is they lack the ability for a user to ADD a row.
Example: If I give colleagues a filtered view of data that are relevant to them (say, from an underlying sheet they don't have access to), they can easily edit rows that exist but can't add rows without leaving the sheet and accessing a form.
That friction makes them less likely to add data. Especially when using the mobile app where they can't have multiple tabs open simultaneously (there's another idea).
I imagine adding this ability is complicated for many reasons. BUT a simple solution is to provide for a big + button on the page that can pull up a form.
