I have used Google Drive for a long time because the school I graduated from allows me to keep using it lol.

Google Drive is easy to use and to share a file with people, however, there isn’t an easy way to check whom I shared files.
Actually, there are some services to do that like below.
I used to use google-drive-permission-search because at that time I used Ruby as the main language. But, I haven’t used it for a while 😂 and recently I use js/ts and python mainly. Also, my goal is to pass Google Drive’s permission check functionality to…

I have used BigSur for a couple of months and so far so good. There is one thing that I regret. It is that I cannot build openFrameworks on BigSur 😭

Then I have followed the one issue on GitHub.

Amazingly, this issue was solved by @ofTheo.

In the issue, he said he would work on a PR for this for the patch-release branch / 0.11.1.
