I have added a link to this thread from documentation and some additional information
Thanks for linking and also your additional infos - you saved me some work

Sonar is periodically putting garbage into parameter names.
i have never seen that - is this only with Platinum?
editor can not load the file then (with xml parser error). I do not have an example (I have solved the problem with my xml in-between), but may be you load the file as UTF8. I guess Sonar understand and generate at most 8859-1, so some not valid for UTF codes can appear.
if this happens again, please send me example XML.
i
have to read it as UTF8, because it declares itself as such: <?xml version="1.0" encoding="UTF-8"?>
i´m using MSXML-lib, which does this automatically. Maybe it fails if content does not match the encoding, but i´ve never seen this before.
1) an option to remove plug-in information from the file.
this is already done for next version.
The editor tries to avoid errors with removed params. if it finds params which are currently not assigned, they get assigned after the last used slider. And because also empty places are not valid in generic.xml (i´ve tried everything i could think of), i´ve included the "check" (which is also done on saving). This ensures that any empty places in the current layout is filled with neighbour-params, so the layout stays the same. Otherwise all following params would get shifted.
And duplicate params are perfectly valid (at least on X3) - that´s what i use all the time. I often use some "dummy" param to fill gaps if i want a specific layout. Let´s say i have an EQ with 4 bands, but my BCR has 8 columns. To get the layout similar to PlugIN-UI, i have to fill the 4 right columns with these dummy params.
save "Follow AZCtrl" and "Always on top" settings
will be in next version
another row for sliders 9-16.
i´ve been experimenting with a more generic UI, but have to do i little bit more.
make XML file text editor friendly
i know - it´s just a stylesheet missing.
I use notepad++ (not only for XML) - it´s just one command to get XML "pretty-print".
thanks for your feedback!
