Just wanna say I thought this was a pretty neat player on Windows. On mac it's even better I feel like it could give foobar a run for its money when playing certain content. I was looking for a good player for longforn content with a good speedup and remembering the position and Fastplay is perfect for this.

2 quick bug reports: 1, I'm guessing you probably already caught this one, speech only works in the main window so if you set up global hotkeys to read things or use the sliders there's no speech. You're probably going to need either the applescript workaround or just using the speech synth for outside the window which I think for this is a very valid usecase.
2: Audio files from the Podcast I help to cohost don't play and insta crash the app. Do a podcast search for tyflopodcast, and then try to play one of the episodes starting with tyfloprzegląd. This happens both if I play from the podcasts view or if I first download the file and then play with Command+O. Other podcasts like Applevis work, so does playing it on Windows though it seems chapter navigation is only available when the episode is downloaded, don't know if that's an intentional limitation.

Also, where do you prefer to get reports like this, on here or as git issues?

Either way thanks for some really awesome apps. FastGH is also very quickly becoming a favorite :)
