I would like to confirm what the above poster said as for me Ctrl Z also works well and will go back a long long way, can't say how far for sure but it seems like miles. Ctrl Z will be second nature to all you MS Excel users out there.
I'm sure that it (and its more attractive cousin, command-z
) is second nature to anyone who's used a computer much over the last two decades, but it doesn't address the original point. I've often found that I make a change, make more changes and then want to remove the effect of the first. I know that I can simply return the appropriate slider to its earlier position, but I'd still like to be able simply to delete the change.
The UI needn't be ugly. Click on the line in the history you want to remove and hit the delete key. Bang: it disappears, its effect disappears, LR highlights the line which was previously above or below it. The history is stored as a linear list of instructions, so that instruction is deleted from the list. All is now as if that line had never been.
We're not, as I understand it, wanting to edit the history while retaining the effect of the deleted lines. I agree that that would be hideous, both conceptually and practically.
If history is intended as an audit trail, then of course what I suggest would be a very Bad Thing. But it isn't; it's just a way of going back in time. I really don't see the downside to this feature, which I suggested here some years ago, I think when LR1 first apperaed (and received the same reply from Jeff, by the way). I realise it's not going to happen, though.
