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.
Jumping back on that topic. It would be extremely useful to leverage the waiting message to rotate tips about metabase usage, it's a common practice in the video gaming industry.
Messages could be standard across instances and set by metabase to do Product Marketing.
Also which would be better for us, would be to let the admin define a list of message to rotate. Something like :
To analyse user retention refer to this Model
This metric is defined in this model with this definition
