This is okay:
[MinAppVersionWin]=3.26
But what about?
[MinAppVersionMac]=1.x.x
What's the min version for Mac?
I’ve added this with 1.5.0 but you probably already have a later version because of the settings feature.
Yeah, it's 3.26. Thanks.
Is there any way to display an 
if there's no coverart.
Here's what I have:
json_select "release_image_uri" # _COVERURL
IfLess 1
Say "❎"
Else
SayRest
EndIf
Say "|"
See the blank coverart here. I would like to put the same in there.
It’s not possible - except to store it as an image on a server, which I don’t recommend.
Okay. Just thought it would be nice to display something in place of a blank square.
Is a min version necessary for the thumbnail feature? I added it to my script years ago and it did not effect the Windows version.
No, it’s not necessary – only if you want the cover thumbnails to appear is v3.26 needed. It’s just ignored on previous versions.
