I like the idea behind this extension and the options for it are simple, so it's hassle-free and low effort.

However, whenever it sends me a notification, the study is already full, every time, after my initial use for over a week. Other surveys it outright wouldn't tell me about.

I find it necessary to keep a pinned tab open and manually check it myself every hour or so, because this app is inadiquate but does remind me to check. It would be nice to be able to make it check more frequently than every 60 seconds.
