Hi McMakkonen, welcome to the Sony Forums.
It's true that PMB is limited in functionality but I've found this to be true of all free bundled software. To be fair, manufacturers make sure bundled software works in a basic, functional way and aim keep it simple for non-expert users.
Sometimes this leaves a lot to be desired, depending on your expectations and level of expertese. Being quite fussy, I generally go for the best I can afford
but there are some very low-cost options from a whole raft of developers. Sony's creative suite can be found here.
Hope you find something that works for you.
Cheers
Mick
