Tidy set-up.
But i would not advise you running too much current through your 'un-coiled' extension, under your desk, as it can can act as a coil and give you all sorts of problems with irregular voltages and even heat (at its extreme)
All extension cables, should (theoretically) be laid out and not wound together (it's ok with low current but if you are pulling a substantial load, then i would advise you to either, unravil it or replace it with a smaller extension lead.
