I don‘t know whether you have already thought about it, but I would genuinely love to have an option to temporarily save tasting notes as draft before submission to the xchange thread. I often experience cases where I want to look up previous tasting notes for comparison while being in the middle of writing down a tasting note. Currently there is no other way than discarding the tasting note and to start from scratch again…
At the very bottom of the tasting screen you have the possibility to decide if it shall stay private or be published. I use this function for my drafts.
I guess, this is a reasonable workaround but the save draft option would still be my preferred choice as it would be easier to handle, also when you want to jump between different parallel tastings or when you want to publish in ‚bulk‘.
