Symbol Editor - Cut command without paste lost cut symbol

[Silviu Laurentiu]

 _ Go to Symbol Editor
 _ Select a component, press mouse right click on it and select Cut command
 _ The components will be deleted from library, even if it is not pasted yet
 _ Save the library from where cut the symbol.
 _ If the Symbol Editor will be closed and then opened again, the symbol cut before will not be available even if a paste command will be tried.
 From my opinion this is not a safety behavior because the symbol will be lost if it will not be pasted.

Confirmed. Also in my opinion, wherever things are "cut", they should remain visible until they are pasted, but in some way highlighted (various other programs use italics / lighter color / dotted borders / etc). That way, you can visually keep track of what you just cut and are preparing to paste.

I think Jon's suggestion while handy, would be too non-standard.

However, Cut/Copy/Paste of symbols should be using the system clipboard, which wouldn't have this issue. The current implementation uses a simple global variable.

Changing importance to "high" as this can be a data loss issue.

The fix for this turned out to be based on some of Jon's net/bus changes, so it can't go to 5.1.1 after all.
