I use shapr3d daily. Hereby a few updates that would be really helpful.
1- copying one object or a selection of objects into another file.
2- A object library from where you can import elements in your document would be very helpful. When a individual part or document is changed it should also change in the main linked document. This would be a very helpful tool
3- Making a part invisible just by clicking on it. I notice i always move objects away when I need to be somewhere behind it. It showed faster then using the menu. It would be very helpful if you could click on a object and remove it directly there.
4- As mentioned in the other topic the selection tool should really be updated. It can be very very frustrating at the moment.
5- DIMENSIONS OUTPUT!! (Like fusion360)
