weird label orientation
Since http://git.xfce.org/panel-plugins/xfce4-cpufreq-plugin/commit/?id=6836d994bb9191e5b16838d1fcfcbf23bc4ba99d the plugin orientates the CPU frequency label according to the panel orientation.
I don't see why this could be useful at least it isn't useful in general.
See attached screenshot of my panel, I have a vertical panel but all labels are horizontal. Otherwise they are very hard to read and take more vertical space.
What's even worse, if the panel is not full size, i.e. does not take any vertical space available, when the CPU frequency is changing, the frequency label is also changing (in my case e.g. from 1 GHz to 2.4 GHz) and so the necessary vertical space of the panel varies according to the current frequency. This causes of resize actions of the panel which is very annoying and distracting.
I'd vote for reverting the part of the orientation of the label or at least make it configurable.
I would vote for keeping the current setup (display the text in the same orientation as the panel) or make it configurable.
This works as intended and follows the HIG. You can set your panel (>=4.9) to deskbar mode instead of vertical mode, I think that is more to your liking.
