Hey Dave -
Just to clarify the “ask” on this post was to add support for allowing page developers to write their own Formula Functions and “register them” so that they can be used on a page. This would be very similar to writing a custom component and registering it for use. Being able to write and register custom formulas would provide infinite possibilities with regards to formula support without having to wait for skuid to add these to the core product.
That said, ISBLANK() and/or ISNULL would be welcome additions to the stock formula support. If what you were asking for in your post was to have Skuid add these to the stock formulas, I’d recommend posting another issue asking for these (I’d vote for it :))!
