Ignore List - All but one folder

Hi there, new here

Insync is great. I’m trying to setup with Google Teams, but having a problem with ignore rules.
First, it would be great to have advanced ignore rules such as size and to differentiate paths, files and folder.
Second, I’m trying to sync only folders named “design”, but to no avail. Shouldn’t the following rule work:
[!design]*
Third, if I add the rule "images" do not upload shouldn’t files in folder imagesnot be uploaded? Not working

Thanks
