Hi! Connect dials with local files is available on Chrome and Opera. This function is not supported in Firefox version 57 and next. To connect dials with locals on Chrome or Opera you need to open window "Add Site" and on the right top of this window you will have a small instruction how can you add your local file to dial. The easiest way is to pull your file to your browser then you will have its URL on address bar. Put this URL in URL-bar in window "Add site" and get your dial with local file.  

Hello! Can you tell what happens when you open dial with ctrl+click? I used this combination and got a new tab. About shift+click i have already sent request to our programmers. In addition you can use mouse wheel click besides combinations to open a new tab. 

Hello! Try to switch off the auto update of dials in the main settings.
