Pushbutton flow
Although buttons are nice, sometimes you simply want a TOGGLE button.
This flow allows for that.
Read the COMMENT node at the top for all the variables used/needed.
I have NOT allowed for any null entries. You must fill them all in. Except for the topic file. That has a kind of built in "if nothing entered" bit.
There is a button node which is set up ready for use. All you need to do is set the size and on which dashboard it lives.
The main set up is in the SETUP function node. There, there is a list of what is needed to be set up.
Examples are in there now.
