Welcome to the BitShares ecosystem!
Those are some of good ideas sir, particularly the idea of coupling UIAs with a simple wallet. Having it be as easy as tweaking a config file to setup that universal wallet is also an awesome concept.
I don't recall the details off the top of my head, but a simple vs trade view was added fairly recently to the UI, and it has been well received.
I don't know how easy it would be to create what we call a "light wallet" to highlight or focus on a specific asset (or assetS) using a config file, but it's a very interesting idea I hope
@svk will comment on.
Thanks for sharing, and once again - welcome aboard.
PS - It occurs to me that with UIAs and your mentioning of how quickly you find the rabbit hole can get deep, that is especially true of UIAs. Thus to keep your idea effective I think you have to split USERS of the UIAs to which this simple wallet is targeting away from CREATORS of those tokens. To actually create the tokens requires deeper knowledge and understanding than would fit well with the user wallet.
