1) position of pasted module

On the other hand, if MG drops modules into the "soonest" open and properly-sized slot, you know where they are.

In my case i pasted a 1 HP spacer module 6 times in a huge rack that has been 95% full with modules
it took me several minutes to locate where those have been pasted and move it to the desired position

also the moving of those tiny modules in a huge zoomed out window is very hard to achieve. And the moving wouldn't be necessary at all when it had been pasted in the right place.

So generally i agree but this does not apply to tiny modules in huge racks
Imagine you have a huge rack where you paste > 100 modules
100 times * no need to locate&move module after pasting = lot of time saved

3) links to deleted racks

Uh...do you realize how much storage space that would take up on the server?

yes - very little

rack-id | user-id | deleted
  123   |   456   |    1

so when clicking on a rack-link for example found in the signation of a post in the modwiggler forum
modulargrid.net/e/racks/view/123
you get invalid rack

it would be dead easy to add a link to this page
see all racks of user 456 in case user 456 currently has any public racks
sorry for beeing not clear enough...
