Forget about the product for a second.
Don’t let that stop you.
IMHO learning the basics and then growing from there; does not matter much what app you use.
Many of the basics harken to back-n-da-day when we would physically cut/spice 2 inch tape.
Some of those early techniques can still be applied today.
flaviusr, IMHO it’s like learning to drive a car. Once you have the basics down, you can drive just about any car.
Just take your time and enjoy the learning process.
Reason:
there will be plenty of time later to ‘pull out yer hair’, and yell at the top of your lungs:
‘dis sh!t ain’t working’! Arrrg!!! And then you figure it out. Yay!
Good Luck!
