What do you dislike about PageProof?
Pretty much everything. The animation and the clunkiness of the interface, it's hard to see which comment is related to something drawn on the doc. It's just not an intuitive or nice piece of software to use, Proof HQ is better in every way except price.
If you upload multiple documents you cant see the individual file names without going to page grid.
The tools for marking up feel archaic, I can never tell what tool i have selected because the icons are pretty much identical.
There's no easy way to zoom in and out via key commands.
There are no easy tools for measuring or checking alignment they're buried on clunky menus
If you have a document that happens to use the pageproof background colour there's no way to see the edge of the doc it just blends in.
On the 4th of July they replace your cursor when uploading a proof with a stupid firework animation that means you can't click on anything.
The proof tracking is diabolical, I've been using this for years and I can never find a proof I'm looking for on the dashboard, so we have to result in pasting the relevant latest proof links into a ticket to track them.
In short it's pretty crappy and hasn't improved in years. It's not easy to use, it's been implemented badly, the customer support is okay, unfortunately I have to use it daily. Review collected by and hosted on G2.com.
