Hi,
First of all, congratulations for the new release, it’s awesome and promising.
I’ve tested it (Debian / Chrome) and 2 issues faced (Both worked on earlier versions):
Impossible to create template variables.
Piecharts: position legend to the right side is not working
Are you trying to see template variables for a new or existing dashboard? Any errors in chrome dev tools in console tab? Regarding pie chart are you using latest version?
Please include more information. Do you get any error messages? If you open the chrome dev tools you see any errors logged in the console tab? In network tab are there any bad request?
