I use the app to teach mathematics and computer science lectures to college students in online mode. One very important feature that is missing at present is that students have to use their attention to determine WHERE on the slide or notebook I am presently writing (i.e. they need to determine where new writing is showing up). Whereas, in a physical classroom, it's easy to see where the professor is and where in the blackboard he/she is writing or modifying a diagram. It would be nice if one could have a big red arrow show up wherever I am writing or annotating, so that students can focus all their attention on the important concepts being covered (and not have to figure out where the new writing is showing up). Currently, this can be done on android tablets such as S6 Lite, where apps such as Pentastic let you choose a custom image (such as a red arrow) for the cursor, and one can then teach using note taking apps (such as Squid). If I am annotating a slide or need to point to something I've written earlier, I don't need to click on an icon to switch on the laser pointer - I only need to hover the S-pen over that writing, and the customized cursor (which also functions as a laser pointer) automatically shows up there. Thanks!
