itch.io

In case this helps anyone..

A way to work around this is to install Playnite and install the itch.io plugin, and use Playnite to find your itch.io games, etc.  

If you want to install all itch.io games you don't have installed, then create a filter in Playnite filtering Library by itch.io and check the "Not installed" box.  Then, go down your list and double-click each entry you want to try.  That will pop up the install box in the itch.io app and you can install each item there one by one by one by one by one by one by one by one by ........  Note that a fair amount of the games, books, etc are somehow unable to be installed from the app but most of them work.

(Anyone looking at this has probably figured this out by now but..) If when trying to install something the itch.io app gives you an error something like "Too many HTPP connections", try again, because it means the app is hitting the itch.io website too quickly and the request will probably work if you try again.

It seems like it would be an issue that the developers would like to prioritize, since it makes their app basically useless for anyone with any decently-sized library.  I'll also throw in that the app will take a noticeable amount of CPU even when seemingly idling, with no visible loading of anything or any indication that the app is doing anything at all.  I dare say that the app is badly written as it currently stands and that itch.io's continuing to keep the app as-is (and even their releasing it in its current state) shows that they just don't care.

I also have this same issue.  Closing out the app and reloading it works briefly but the timeouts quickly start occurring again.  It appears to be related to loading new entries in the Library view, which is necessary in order to scroll down to the games I haven't installed yet.

A "Not Installed" filter would be great to work around this, even if the core issue wasn't fixed.
