I have felt in the last year or so Photoshop is simply less polished than it use to be. Computer hardware has improved and given us more cores and faster drives, but photoshop still takes around the same time to open and files seem to take longer to import. Tools seem to glitch out more regularly and the overall interface has barely barely been improved since CS6. I'm pretty unsatisfied with the state of it as a project and hope the stability and performance of Photoshop is something that is addressed and brought to modern standards soon
