I'm not even asking for extra features in Photoshop. Adobe is already King of Bloat, far out-weighing Microsoft in this category.
I'm just asking for core/foundation algorithms to be solid, instead of super-easy, basic, entry-level crap. What Photoshop needs, unfortunately, is to be re-designed from the ground up. Take something like the current filters... Not much has changed in 10 years. They're still modal with completely basic and generally poor interfaces. With each recent version Adobe has tacked on one more intricate and involved filter (such as Liquify, etc..)
Quark suffered a huge blow by not innovating and not taking product release strategy seriously. It's a shame there's no one around to do the same to Adobe on other fronts. Don't even get me started on GoLive! And what exactly in an Acrobat Pro install requires more than 400MB of disk space?
