As of version 216.2 of the iOS Dropbox app released the other day, iOS 14 widgets have been added to the Dropbox app for doing specific actions and see overall recent changes in your Dropbox as a whole. However, there isn't a widget to limit the list of changes to a particular folder, which means the widget isn't very useful if you have automatic photo uploads turned on, as the widget is mostly just a list of recent photos (similar to the website homepage).
It would be great if a new widget could be added so that I can see recent changes for a specific folder in my Dropbox, such as one that is a collaboration with other users. Instead of a new widget, the existing "Recents" widgets could have an additional setting added to pick a specific folder over everything.
Currently, I replicate this functionality with IFTTT where a folder on Dropbox is monitored and then push notifications are sent to the IFTTT app to notify me of changes when they're made, but this has limitations and is also per-file rather than grouped by time and/or collaborator. Plus, IFTTT have started charging to use their service with more than a few applets, so it would be better if this was baked into Dropbox widgets itself.
