It might not have been a generally obvious problem when dealing with short source files, but with longer files (like several minutes long), the offline processing chain in HourGlass can take quite a lot of time relatively speaking to process. This can be problematic if the processing is done in the same thread that deals with the graphical user interface, as buttons will be stuck etc. I preliminarily worked on making the offline chain process in another thread now and the results seem encouraging! The file that’s loaded is almost 3 minutes long, but I can keep on clicking around the GUI even if those actions trigger a recalculation of the offline chain. (click the image for animation)
