Hello - Spark seems like it could be a powerful tool for mechanical design work. Our team enjoys the group chatting, and sharing images features. What I want to know: 1) how do I QUICKLY copy and paste an image within spark? (e.g. I want to take an image from one space and share it with someone, or point back to an image from a few days prior - how do i copy and paste ??); and 2) with an image, how do I draw on it? for mechanical folks, its really important to be able to open up an image, point to something, and sketch right on it.... seems like it should be basic built in functionality. Is this possible?
