That is a very good question. Short answer: I don’t know as I am not familiar with the project.

I have had a brief look at the issue tracker and it doesn’t seem to be mentioned on there. Perhaps I will raise an issue later when I am at my computer (or if anyone else beats me to it then please feel free).

How long is “a while”? I’ve had it open for around 30 minutes now and I’m not seeing what you’re describing. Around the 15 minute mark I also tried clicking through various tabs, performing some actions, etc. and memory usage is still staying steady at 247MiB.
