Having used CSP for a couple of weeks now, I have a few things I'd like to see done differently.
It's a very nice piece of software, but it's file handling isn't as strong as Photoshop's.
1. CSP does not allow you to save or load .tif files with layers. (It automatically merges all layers incoming and outgoing).
2. CSP doesn't allow the use of file compression (such as LZW compression) when using .tif or .psd files. This results in huge, unwieldy files; 60Mb rather than 12 Mb for my projects, for instance.
3. Only the native file format, (.lip) allows for efficient file saving, (using both compression AND layers). Being unable to use generic formats is VERY annoying.
It is safe to say that NO print agency in the West will know what to do with a .lip file, (the native CSP format), and this means Photoshop or other software is still necessary to prepare files for press. Similarly, putting files together in book layout software like InDesign requires generic or other Adobe formats, and CSP has been, it seems, deliberately designed in such a way which makes this unnecessarily difficult.
I have found these limitations to actually be annoying enough that my use of CSP has fallen off and I'm returning to other, less graphically capable software which is nonetheless better at file handling. The tool which is annoying to use doesn't get used.
CSP would definitely be improved if it allowed for the user to create generic file formats (without handicaps).
