Increase history items for "cell near" context

Dear Joao,

I work a lot with Context "Cell Near" e.g. to detect work places,...

To set the cells for my wifes place I look at the context in the evening when she comes home.

Sadly the history (in the cell near context magnifying glass) is to short and so does not show the cells from in the morning. Could you please at least double, better tripple the history or make it a preference.
