Easiest way is to open bag on the same layer like is bag widget. But if you have another layer which is above layer with bag widget then widgets on the higher layers will cover opened bag. This is problem in play mode. But in design mode it could be ok. And in play mode I can draw on system reserved layer like it is now. This could work fine…i think 😉 There is another problem, you can’t move widgets to bag from another layer, but I’ll not fix that now, there is small workaround with import widgets function from another layout.
