After you record your Flow, you can edit your screenshots with an external image editor. Click on the slide to which you wish to add something. Click on the Color Palette icon above the screenshot (“Edit image in external tool”).
The screenshot will open in Microsoft Paint and you can use it to draw something into the screenshot, mark it with shapes, or insert additional text boxes.
When you are finished editing, click “Save” in the upper left corner of the screen and then close the Paint window. Your changes are automatically transferred to FlowShare.
If you want to remove the markings, click on the crossed out Color palette icon (“Discard drawings”).
