Adding an option to interrupt viewing a variable?

[NirOfir]

I would sometime click by mistake on a large matrix (say 1,200,000X10), causing Positron to become unresponsive as it tries to expand the variable. In those cases, it would be nice to either have a way to interrupt the process or at least have a warning pop up "Variable X is very large. Viewing it could be very slow. Are you sure you want to proceed?" or something like that.

Thanks!

Thanks, I've filed this as #12622!

How long does this take on your machine, and what version of Positron are you using?

I used this matrix:

m <- matrix(rnorm(1200000 * 10), nrow = 1200000, ncol = 10)

and expansion takes ~300ms for me. Can you share any of the code used to generate your matrix?
