This feedback is not coming from a producer - I’m a startup founder with a filmmaking background, but I thought I’d share some initial impressions in case any of it is useful.
Within the first 5 minutes, I found myself looking for a circular undo icon somewhere in the top-right corner. Later, I realised I could just use Command + Z, so that solved it.... but thought I'd still mention this if it would still be worth including such a button.
Also within the first 5 minutes, I started looking for the opposite of the expand button. For example, a way to drag and drop two rows into a third row to group them together, like creating a folder. Something similar to the right click + “Create folder with selected items” function on Mac.
Within about 10 minutes, I searched for the ability to paste longer text into a field that could be expanded if needed. For example, when adding more detailed task information of what was included in a quote. I ended up putting the text into the name field in the most expanded folder (that felt like a good placement), but it gets cut off.
