Since Lubuntu changes its desktop from LXDE to LXQt there have been changes in icons of the panel and PCmanFM, the file manager. I am not an experienced user but I am wondering why a change in technology also has to come with changes in the look and feel of the desktop environment.
Especially when Lubuntu 18.10 is also using PCmanFM (qt version) I don't understand why PCmanFM does not simply look as clean as it did in 18.04.
Is there a way to use settings, e.g. openbox configuration manager or others, to make the new Lubuntu look like the last one(s)?
