Hello there. Hope you are well.
Just tried QDock 1.67 and I have to say that the improvements are great. Positioning works fine now by just using the asterisk and if you reboot, it re appears exactly where you had it. Responsiveness has also been greatly improved!!! Well done. Drop on icon feature works fine (except my app).
One small thing regarding positioning. When I position let's say the dock to be in the middle of the lower part of the screen and I add or remove apps on there, the icons are added but the central positioning of the dock is lost and you have to repositioning it with the asterisk. Would be nice to be able for the dock to keep it's position and add the apps centering it's position automatically.
Anyhow the dock works fine now and it is a pleasure to use it. Well done again
