It is admittedly a small request, and I would understand if it takes a low place on the Real Soon Now collection of "round tuits" to ever be implemented, but I figure it can't hurt to ask.
The current statement when waiting on Metabase to retrieve underlying data from the database is "Doing Science." It would be very cool if we could customize the message. In my case I would change it to Working Magic especially given the late Sir Arthur C. Clarke's observation that "any technology sufficiently advanced is indistinguishable from magic." And for the end users, what is produced IS magic. The magic of Metabase.
Thanks for the consideration.
