I'm still expecting an independence referendum to be the price for SNP support in the event of another hung parliament.
The SNP are undoubtedly keen for another one: partly to avoid losing EU membership status, partly because some of their hard core support are demanding one right now and have done ever since the last time, partly because their 2016 Scottish parliament manifesto says they will seek one if there's a "material change" in circumstances such as Brexit (I suspect this was put in to give them an excuse to call for one if it went that way, otherwise they wouldn't have bothered until they were sure there's enough support to win a second referendum) and partly because independence is their raison d'etre.
I suspect a second referendum without Westminster's approval would simply not be recognised.
That does not diminish the fact that it still has not been resolved if the Scotland has the actual power to to decide for themselves, only the Supreme Court can rule on that one as it’s never been tested.
You also have to remember the power of unlimited parliamentary sovereignty is an English principle not a Scottish one as it has no equivalent in the Scottish Constitution (MacCormick v. Lord Advocate (1953) SC 396 - Court of Session (on appeal) it also comes down to the fact England itself also cannot declare if it also wants to leave the Union as it has no devolved parliment unlike Northern Ireland & Scotland
