If my Geoprocessing pane is on auto-hide and I want to populate an input box with the help of the “Browse…” button (on the right side of the input box) I get an open data dialog. This dialog is modal, so the pane remains open until the dialog is closed. But after I close the dialog the geoprocessing pane immediately goes to hidden state. So I have to “re-unhide” it. I would be more convenient if the auto-hide panes remain open if a user uses a model dialog opened from the pane. If you populate the inputs of a gp you won't close and open it several times.
