Tried out experimental and found a few issues you might not know all of:
1. You can no longer space out the card by adding spaces on either side of the title
2. Can't set the colour of the joker text nor its outline
3. Tried to use a square image (like photograph is not the normal ratio) and it was stretched (I think, maybe just cropped?)
I'm still very happy with the tool! But I ended up using the non experimental version for my needs this time. Looking forward to the day your tool is all anyone needs!
