May I suggest a small change in UI for tyFlow main window?

and always visible above all drop down menus

I'm not sure what you mean by this...

Also you can quickly enable/disable a flow by clicking the red/green circle in the top right of the editor grid. That's faster than navigating to any menu...

I mean add radio buttons for Enabled/Disabled/Enabled(render only) above Editor menu (See image attached). The problem I am experiencing now is enabling/disabling about 20 tyFlow setups in my scene when I need to do that.
