- In the Display section of System Settings, there is a warning about the lack of kcm_randr. In KDE 4.11 it was actually replaced by kscreen.
- The password input box in LightDM has no focus, i.e. one has to always click it before being allowed to type
- The new task manager has no trhobber/spinner animation and some users may think, that after clicking an icon nothing is happening. This feature, however, does work properly in the standard task manager.
- Big thumbs up for the new Plasma theme and LightDM, but the previous window decoration could stay for a while. Forman looks much better than GNOME 3 (highly subjective opinion)
- Also, I would like to suggest changing the animation render’s speed from Instant to very fast. The latter is optimal, as users will not notice any sorts of lags, but also will be able to clearly see the animations and appreciate them (at times, they are virtually invisible on Instant)
