Somewhat. His post from Dec 30 listed three issues:

-  IDE spams a lot of IDE only messages when creating many objects by
    script -> remedy: Lock messages
Locking messages is a good habit for any context in which system 
messages are not needed.

-  Nested Lock screens are a big "NO-NO“ nowadays
As Mark Waddingham noted, with hi-res displays there is now more impact 
from rendering; 4x more pixels to push.

-  Array operations on larger data sets still slower than they were
Already in progress - see:
https://quality.livecode.com/show_bug.cgi?id=16387
https://github.com/livecode/livecode/pull/6671

All three issues which began this thread are resolved.

The rest was in reply to his open-ended question at the bottom of that post:

    Did anybody of you happen to refactor old code and if so,
    do you have any observations you might want to share?

I didn't see Malte's mention of PDF in the post that began this thread, 
but topic drift is a natural part of conversation so no worries.

Interesting circumstance in your report.  Lots of moving parts there, 
with LC relying on the browser component which in turn relies on Adobe 
components (and FWIW I share your opinion on Adobe <g>).

Looks like you've made some good progress there.  How can the readers of 
this list help?

Old habits.  The bug database used to be called the "Revolution Quality 
Control Center", and the acronym is forever stuck in my typing fingers.
