It would be useful if the purse could be displayed in the "Survival Inventory" portion of the creative mode menu, because it is cumbersome to switch to survival mode and back to creative mode when mapmaking and testing.

We might look into doing this, as we are changing the purse to an owo-ui component, in order to make it be displayed in Villager Trade screen (see #54). With this in place adding it to the Creative inventory should in theory be possible

Will these changes also be available for 1.19.x? 1.20 is out now, but I don't think about switching yet

I do not believe so, as it depends on features exclusive to owo-lib 0.11.0+, which is only for 1.20.

I cri

Very true. Just as having no display while trading

This has now been implemented in 0.2.10
