At the risk of steering this tread back onto it's original course ...
I find no-copy/no-mod things very frustrating and tend to avoid them if I can. But I also tend to find no-transfer items frustrating when shopping for a gift. Unfortunately, I don't think there will be a good solution to these problems until Linden Lab makes some changes. Here are some frustrations I have, and how I feel they can be resolved.
NO-COPYFrustration: No-copy perms are frustrating for somebody like me because I like to mix and match items from various outfits to create my own unique looks. Lacking copy perms means I have to
move a skirt out of it's original folder into my outfit folder, breaking the original outfit. Worse still, I cannot use the same skirt in more than one custom outfit. If I have mod rights, but lack copy rights, then I cannot even back up the original and I risk ruining an item if I change it.
Solution: Inventory shortcuts. When I right click on a no-copy item (or any item) I should get the option to "Copy Shortcut." When I paste the shortcut into a folder I would be pasting a link to the original item (actually the item's key so that if the item is moved the shortcut isn't broken). This way I can leave the skirt in it's original folder and use it in many custom outfits. I would also love it if the "Create Outfit" feature of the Appearances dialog created a folder of shortcuts, rather than moving items and destroying the original sets.
NO-MODFrustration: No-mod items, particularly clothing or attachments made from prim, are frustrating because not every avatar shape is identical. I have purchased many boots and prim skirts that were ultimately useless to me because I could not fit them to my shape (no, my booty isn't
that big!). At the same time I recognize that many designers make a good living selling color and texture variations of their items.
Solution: More granularity in permissions. Presently items are either mod, or no-mod. I would like to see each tab of the edit dialog addressed with a separate mod perm. So, for example, an item could be "object" mod, but "texture" no-mod. This would allow me to size my boots, but not retexture them.
NO-TRANSFER:Frustration: No-transfer items make gifting very frustrating. This hurts both seller and buyer. While many designers are happy to send a gift on your behalf, that kind of spoils the idea of wrapping a gift and watching your friend open it.
Solution: Transfer Complete and Transfer Once. With Transfer Complete perms, if you transfer an items, you transfer all copies of that item. With Transfer Once perms, you can transfer the item one time, and the recipient gets the item as no-transfer.
Anyway, those are my thoughts. As a seller and a shopaholic, I would sure love to see some improvements in the area of perms in a future release.
