Are ALL locations where it writes to disk configurable now?
Caches, Buffers, Logs, etc.
Yes. Now everything should be configurable. @mjitkop please let me know if I got it this time! I added logging. If it does it please send me logs. If you go to the settings page you'll see how!
Nice application. I especially like the "Download" option if I decide to load onto my laptop when I travel. Still wish Channels DVR Download feature was available for us Android users.
I thought I saw that 1.1.4 version fixed the flashing poster images, but I'm still seeing that in my movies library (500+ movies).
Can you send your logs and I'll take a look later. I can only take guesses when I can't repro and I don't have logs from anyone.
When I have a chance later I'm going to re-license this project to MIT. I've been doing too much with various OSS projects lately and family stuff/personal loss and I think I'm burning myself out a little bit. This is the only project I have that people are using that might actually be good and has a restrictive license. So I'm going to open this up to forking and if any devs in the community see value here and would like to be added to the repo to push and build I am 100% open to it.
That seemed to address the issue. Thanks.
Confirmed, no more flashing in the library.
As a future improvement, it would be good to add sorting options in the library.
Been there, done that so I understand. 
Priority to personal life.
I opened the repo up to pull requests if anyone wants to add something like that.
Right now, I have done way too much, so I could use a little bit of a break, personally. I think I was honestly writing a little bit of software to cope/distract, and that's probably not healthy. 
As a future improvement, it would be good to add sorting options in the library.
It was actually pretty trivial to add. So enjoy!
Got bored tonight and it was trivial... macOS and Linux (Flatpak) inbound soon!
