Reload vcd file

[hi0t]

I couldn't find a button or command to reload the vcd. If there is no such function, it would be a good idea to add it. If the data file has been updated, you have to close it, then open it and configure viewing again.

Great idea! I just added it to the issues list as a feature request and tagged you in it. Feel free to discuss further on the issue!
