Mainly needed this for some on-screen widgets in OBS. Unfortunately, it doesn't work as expected.
Example: I wanted to set up a stopwatch widget. Teeboard installs fine, CLR installs fine, OBS is able to read the HTML file for the countdown clock, and shows it in preview. However, no matter what I change the settings to in Teeboard, it only ever shows the default 3-minute orange countdown timer. No amount of fiddling, uninstalling/reinstalling, checking settings etc. fixed the problem, and there appear to be no resources to read up on for this issue, or similar ones.
I'm sure this works for someone, but not for me.
