I would like to donate and cashapp is easiest way. Please let me know! Thank you for such great working ad free software!

Not yet, just Paypal, Patreon, and crypto.  The list is on tixati.com/donate

But, I will see if I can get this CashApp setup so we have another easy option.  I have heard of this one before but don't know much about setting it up.  Things are busy but I will have a closer look within the next few weeks.  So, thanks for the idea/reminder!
