single vs. double click on blocks
When using Visual Studio in design mode, you double click on an item in the Toolbox to add it to your workspace; with Popfly, you single click. Very confusing for people used to working with VS. I double clicked the timer block and found that I had added 2 timers to my Popfly design surface.
Normally, I drag blocks onto the workspace so this isn't a big deal. Still, you may want to reconsider for consistency's sake.
