Make Delete a task and throw it in the Trash become two different options: Delete becomes forever.

Akiflow conflates Delete and Trash, but they mean different things.
A wastebasket or trash metaphor is well understood. You place things into the trash and if you want to permanently delete them, then you "empty" the trash.
Akflow uses "delete" and "deleted" to mean "in the trash". This should be updated to leverage the wastebasket metaphor.

My suggestion is to change Delete to Trash in Akiflow and be consistent. If you remove something from the trash, then it's actually deleted. Or, if you maybe hold down the Option key then Trash command becomes Delete, which means it is permanently deleted, bypassing the trash can.

I would also add the ability to remove items from the trash after 30 days as a settable option.
