Using panels: how does this differ between 1.01x and 1.1?

panels are simple in 1.01x, and you can put the patchmem anywhere you want.

i read that you have to observe one or two rules re: patchmem location , in 1.1
and that control activity is affected by where you put patchmems. this is
important for me because of the structure i've been using.

what are the differences?

nb: i've got used to putting patchmems in their own folder, a 'memory'/patch
     container - i suppose ultimately i could just put the Patch Module in there,
     and have everything else as 'ignorePC'. it makes it easy to manage and view,
     and i can then work all the viewable stuff via the blue background pins: these
     are the only ones that go in+out of the GUI container.
     eg: GUI>patch>DSP (>outski>)

if i have to keep patchmems close to the GUI objects, it means changing all this.

apparently a control 'becomes inactive'(?) when its panel is hidden... i don't know
what that means: its values can't change anymore/remain fixed until the panel is
viewable again? this is at odds with how i've come to think about SE operation.

possible also to summarise here, with other GUI issues that need to be understood?
saw comments re: sizing etc.

**and** please, how 1.1 differs 'under the bonnet', in layman's terms(!), with a bit
of background on how Windows handles graphics,(distinct from other OS) the jargon
and its meaning(oh yes), ...

how it changes from 1.01x onwards - what the microsoft C++ libraries represent, in
this context (separately from having a compiler, SDK etc. installed), -and where/if /what
they have an audio role-
