I originally broke the debugger out as a separate plugin because mixing the code
together was starting to get hopelessly complicated. And I wanted to have the
debugger work with Remo. There are only a few points of contact between the
script editor and the debugger, so it was easy enough to pull these out into an
api. But PowerDebug rapidly took on a life of its own with added features and
more robustness, especially as it evolved the ability to debug standalone

My favorite features of GLX2 are breadcrumbs, handler links, and folders. I
really miss all those when I have to work in the IDE's script editor. OTOH, the
IDE has better search capabilities.

Quite right. And the changes, when they come, aren't usually documented, forcing
a mad scramble and regression test with each new release.

Back on topic, the soft breakpoints set in the editor are stored as custom
properties of the target stack and sometimes don't align properly any more with
the script text. Recompiling the script *should* fix this, but doesn't always do
that. Removing the custom property and setting the breakpoints again should work.
