Why make it configurable instead of upping the limit globally?

[ruslandoga]

Personal preference :) I tried setting the limit higher, to 8000. It looked fine for the flash with a long message, but the flashes with short messages then appeared to be "stuck". I expect the flash to be shown about as long as it takes for me to read it.

[ukutaht]

Fair enough, that makes sense to me :)
