It would be nice to have a link to the currently used CSS file (in particular for the case of an uploaded customised one) from the /manage/layout page for an event.
I know how to find it from the HTML and with browser tools, but a direct link would be a nice service.
Even if I keep a local copy of all my indico-event designs, after some time I need to compare, if there have been changes since my reference version, before starting new edits.
