There are a lot of things needing attention but the first priority of the S3D Development Team is to decide and control the order of attention.
IMHO S3D Terminology needs an overhaul to make it more useful and fit for purpose.
Websters offer:
Items: Objects of attention, concern, or interest
Simply an odd, to a native English speaker, choice of word.
This should be superseded by:
Entities: Things having separate and distinct existence and objective or conceptual reality.
A word used by some Graphics related Software Developers.
I requested, along with a few other aspects, Archiving the Forum by Year to avoid old out of date information being dragged up time and time again. Anyone who has used S3D for a few months may quickly realise how fast things evolve and change.
The co-siting of Shapr3d.app Version History, currently only in the Apple Mobile App Store, to be echoed in the Forum and within the App on the Settings page.
The outcome was that these suggestions made good sense. However it will have to take its place in the Development plan.
At this time is there any point discussing the detail we both would like to see improved?
Still hopeful for significant improvement, but finding iPadOS has delivered some benefits.
Be aware it is understood that iPadOS improvements would address the Items/Folder/Filing aspects of S3D, and is currently undergoing Development progress. changes will hopefully improve how things can be handled within Items. Once again the Development plan will take precedence.
Because the following was composed to cover a similar situation I have C&P it here :
Duplicating Items is not strictly a Feature. but it is possible to Copy Items provided you can deal with various caveats.
The Design/Drawing/Workspace Area, or call it what you will, contains the following:
Axis and Planes each individual Item will remain separate but benefit from being given adequate ID. Keeping the Items list tidy in alphabetical order seems to be good practice.
Folders need careful handling and frequent checks during processing to ensure the results expected are being delivered.
Expand Folders by clicking: 
Proper ID of Content will enable quick selection within Items. This File, is offered within the following Link, Example L10055 x 40 x 5 QBFox Bodies.shapr ](/uploads/short-url/iAlW7we9mEMktu6hcYXACX1PAwo.shapr) use this File to make changes to Folders and review the outcome: Play with this File
I am very much looking forward to being able to Type in annotations and possibly removing the manual aspects of laborious alternative workarounds to entering Text within Designs and Sketches.
