Hello people,

Today I modified a previous version of a schematic, and accidently saved
it on top of the original version (no comment please).

I thought that I could recuperate saving the modified version under
another name, then undo-ing the changes. To my surprise the number of
levels of undo was very limited. So I checked the rc file and found:

; undo-levels number
;
; Determines the number of levels of undo.  Basically this number
decides ; how many backup schematics are saved on disk.
;     
(undo-levels 10)
 
This mentions 'schematics saved on disk'. Q: where? I only found one
(## delimited) copy.

Also, 10 undo levels seems so limited, particularly if panzoom undo
is enabled (by default, it is). Q: why so limited? Are the resources
necessary for undo levels so large? Would it be a problem to have, say,
100 or even 500 undo levels?

Though the changes I had made were minimal, and this was a rare instance
where I made a paper copy of the previous version, I'd like to suggest
enabling more levels by default... Particularly with 'panzoom undo'
enabled.

Thanks,
John
