Hi There- In our shop file names tend to get really, really long, and we often need to save files out in multiple formats and color spaces, without paths or channels. I've noticed that when you uncheck the Alpha Channels check box, and the save as copy checkbox becomes active the filename gets cut off depending on how long it is to include the "-copy" at the end. I see the logic behind this–not wanting to save over an original–but I find it most useless. I've worked around the problem by including a couple scripts that will remove the paths and alpha channels from the files in my actions before saving them, preventing the need to save as a copy in the save dialogue.
However, this is still a nuisance.
I'd like to see a delete alpha channels command in the channels palette, as well as a delete paths command in the paths palette.
