I've noticed that new versions of CherryTree and XnView are available from the developers, but the current versions are not on PortableApps.
Is it appropriate to mention this here, or is it known, and just no time to update them? It's okay either way!
You can always report over here: https://portableapps.com/development/outdated
It's within the Development section
Sometimes, the impossible can become possible, if you're awesome!
Thanks John! That's exactly what I was looking for.
