I was lucky enough to attend PaizoCon 2018 this weekend and to view the "Celebrity Gaming: Pathfinder" event during which I was able to see Syrinscape in action. After being impressed with the versatility and depth of the application, I suggested to Benjamin that they might include a "Recently Used" tab that would allow users that took the time to pre-create the session's Syrinscapes but also had to improvise up some additional sounds during the session, allowing for a single spot to find all of the sounds that have been used so far without jumping to too many other tabs.
Benjamin asked me to submit it as a suggestion so I did!
Thank you again for creating such a wonderful system run add to the experience of RPGs.
Good idea. This would be useful.
