Refactoring is your friend / moving from 6.x to 9.x

Malte,

So happy that you're back here my friend. I too spent some time away.

So, refactoring and constantly trying to erase mistakes of my past 
coding self are a constant here. I wish we had better refactoring tools 
so that we could rename a handler and all code that called that handler 
was fixed, or stuff such as rename variable...

Cheers

The stack was somewhat between acceptable and snappy in the 6.x engine series, rather unusable on 8 and on 9. This basically led to so much frustration that I basically gave up on the project, coding and LiveCode as a whole.

It seems I do owe the 9.x engine an apology, expecting everything to work as it used to in 6 is not the way I should have gone. After a refactor of my scripts I am now sitting with a version of my stack that works faster as it did in 5.x / 6.x.
