But personally i twould be nice if you can configure keybinders to your quicklaunchers

I like the separation personally. It’s one of the main reasons I chose LXDE and then LXQt, as I hated the docker approach to task management. It would be a nice feature, but it’s not one I’d use myself, and I’d still like the option of the traditional quick launch approach.

I like it the way it is but some way of quicklaunching is needed. Maybe a dropdown menu for the quicklaunch items.

Probably, no LXQt dev will be motivated to do it when there is no consensus about it. I also disliked quick-launches similar to that of KDE.
