While the idea of heaving a convergence plot for the energy or the force is in principle nice, I would remove this tab for the moment until this feature is implemented since it just causes confusion for new users when nothing is shown there.
Basic implementation on UI-ImGui with c9761e45e0e8286d6db3e4d96a22c8f61b979b15 on branch 'feature-imgui'.
Not yet working in all use cases, i.e. it still has some bugs.
