To say the truth, I have never used preset browser in MX, if it has one. I use MX in Komplete Kontrol and it provides preset browser with filter, favorites. This browser might possibly be even better. But any SW might be possibly better. And more possibilities does not always mean better value for majority of users. There is also tradeoff between ease of use, learning curve and so... and program complexity... But I understand, You have different needs. And different expectations.
