Many thanks for the contructive feedback. Some of what you mentioned have already been addressed in our new release. (There is definitely a new version coming soon!) And the others that need to be fixed/implemented will be seriously considered and hit on ASAP. There're some great ideas in your post.
Additionally most of the reamaining features you asked about (Pause/Stop/etc.) are indeed there, unfortunately, since we never got around to completing the proper documentation, there's no obvious way for the user to know. (PAUSE for example is done by holding the PLAY button for 2 seconds.) Working on getting that out with the new release!
Time has been our biggest contraint in this project and we hope to make a strong push this coming Spring to get things moving faster again.
More very shortly on our new release. And thanks again for your valuable feedback. I for one really appreicate you talking the time to relay what you've found.
Please check in with us again as you use the software.
