Created attachment 2428 screenshot with plugins layout Xubuntu 9.04, xfce 4.6.1. I put on panel(vertical location in my case, please look at attached picture) sytemload and netload plugins. As I familiar with this plugins and economize place on panel I do not use labels. At picture: 1 - is netload plugin. laconical and tiny in size. 2 - is systemload plugin. used extra places between process strides. Expected: systemload plugin should takes not more than netload plugin. Process-strides should be layouted without extra spaces between.
i can confirm this. making all meters uniformly spaced can make xfce desktop look more polished.
