This is one of those subject areas that could be contentious, because I know everyone has their own way of doing things, but there are certain things I *can't stand* when having to open and work with other designers' files.

- Not using master pages
- Not using style sheets
- Not using baseline grid for typography
- Using white filled boxes to blank out bits of the pasteboard instead of sizing objects correctly in the first place
- Importing RGB images at 72dpi
- Importing images from CD/DVD instead of collecting for output
- Rubbish filenames - final version, final final version, final final version 2
