mac'finder needs better undo or trash backup

7.19: mis.addn/mac/finder needs better undo or trash backup:

. I should have fixed that cranky card drive

so it would fit the usb socket:

it has this habit of spontaniously losing its connection

-- sometimes during a folder transfer --

so that it will leave an empty folder at the destination;

then when you try the transfer over again,

it says you're overwriting a folder of the same name .

. if you're sure it's from connection loss,

then it's safe to overwrite,

but if your downloading a camera folder,

and didn't rename the last download,

then you need to stop and rename .

. in this case I had both a connection problem,

and I'd forgotten that I recently downloaded without renaming,

so I accidently overwrote this morning's photo' set

with the most recent photo download .

mac does the strangest undo:

. I was hoping I could do something user-friendly on the mac

like cure an accidental overwrite with a simple undo;

unfortunately, even the 10th version of mr.user-friendly

is falling flat on its iconic smiley face .

. the undo returns the moved folder to it's original location;

but, it has not returned the overwritten folder to the mov's destination;

so, try undo again, then it asks for admn permission .

. OK'ing that, I then notice the overwritten has appeared since then

and is now being removed? did I see that right? .

. testing again, I see what happens is that

the next undo (cmd-z) is actually an undo the undo: [redo mov] .

. I'm really surprised that

while the cocoa frameworks supports infinite undo,

the system finder doesn't take advantage of it .

. this is the same stupid behaviour you get from ms`dos:

it has a trash can for things you delete,

but not for things your app's will delete with an overwrite .

. that should be my highest developer priority:

a suite of common app's that provide universal undelete .

. instead of asking you those stupid questions,

it simply renames your name-clashes

unless you ask for clashes to be moved to trash .

. it also offers to do an ms`dos-style merge of clashing folders

if you set the configuration that way:

this merges an subfolders that have clashing names,

and unlike ms`dos,

it will rename filename clashes during a merge

unless you ask for clashing folders to be moved to trash .
