Set vault timeout to "Never", yet need to type master password over and over again

But you do not like typing it, and actively take steps to avoid having to type it (thereby reducing vault security). Besides, if it was not randomly generated (e.g., %7r4J#0xR$pJr7), then it is not as secure as you think it is. On the other hand, if your “super long, super complex” master password was in fact randomly generated (i.e., using a cryptographically secure pseudo-random number generator, or a true entropy source such as dice rolls), then you can probably shorten it considerably (e.g., just use the first 8 characters, which should greatly simplify typing).
