Never say never, right? But the Pen-Only Toolbar is written in a language that isn't currently compatible with Macs or iOS, as far as I know. That's a mighty big hurdle.
There is another completed version we've been working on though, that I need to share. It's got some audio-feedback improvements for the visually impaired, as well Tool Tips, a completely revamped and infinitely-easier-to-understand Menu system, and (most interesting to me) an entirely new drag-and-drop method to make Hover Icons that is waaaaaaaay easier understand and manipulate. After the bar itself, the Hover Icons provide the greatest leap in general Artrage functionality, IMO. These new Hover Icons should allow a lot more to explore their usage more easily. I need to make videos though, so I'm waiting for some free time this week.
Life is actually slowing down a lot, recently, as I've removed a great many things from my plate (that I put there myself). I anticipate new AR videos in general over the next few months. The little YouTube channel has been watched a lot more than I had anticipated (200 subscribers, and about 15,0000 views!.... THAT'S COOL!), and clearly people find the videos useful. So, I'll probably share more.
