Change color/text on some lines/arrows

Hi Adrai,
Thanks for creating this awesome tool!

I have some flowcharts where I need to add some text along some of the arrows (like labels along the arrow) and some where I need to display the arrow using a specific/different color. I see in your example that you are able to add text to the arrows going out of a condition box, but did not see any way to add a text for an arrow going out of an operation box, which is what I need to do. Can you please advise how I might be able to add text label to an arrow after operation box and to maybe change its color as well.

Once again, thanks a lot for creating this.
Cheers!
