Creating an Undo palette

[Bob Sneidar]

Right. Now imagine all kinds of imported images, and all the buttons or backgrounds that use them in a complex app. Ick! You would have to relink all the objects with their new image ID's. This at least is a great reason to update how Livecode accesses images and icons. A button ought to be able to access an image file right off the disk, and maintain the zoom ratio and cropping to fit the button or graphic object. 

It is also a lesson for developers of livecode: We probably should get in the habit of keeping a pristine template stack for every project we produce so we can go back and "reset" the ID's of everything. 

But all this is moot if Runrev would come up with a way to reset the id counter, or else use the lowest unused ID when creating objects instead of a simple increment off the stack ID. Seems like a simple thing to do...

So for example, if you start with 1002 and create and delete the same object 10 times so you're up to 1012, you can't set the ID of a stack to anything earlier than 1012. Worse yet, if you set the ID of a stack to 10000, you can't reset the ID back before 10000 even if you haven't added any objects. The only thing you can do to "reset" the ids, is to copy all the objects from one stack to a brand new stack (which will give them all brand new IDs).
