Could you include dashes and dotted lines for Shapes, i.e. square, circles, etc? I am not sure why this feature is absent and have been drawing boxes using 4 dashed lines manually and its very unproductive.
btw, I have been a registered user of Snagit since version 5 or 6.
I have also been looking for this feature. I've been a user since version 8 and with all the cool features that have been added since then I'm surprised this has not been added. If you are reading this message and agree with this request, please "like" this idea so it gets the attention of the developers.
