Quote -  I agree. I have my content in separate runtimes too.
As for the slider.  The libraryhelper python script from rdna by semidieu has lovely wide scroll slider that looks very mac like on  my mac - pretty blue and the same colour and size as in safari.  very nice to use.  Unfortunately the drawbacks of the semidieu library script is that undo doesn't work and also you can't add new runtime folders this way.  I do like the sliders though and also can conform as one loads the library object - makes things very quick.
Love esther

Which libraryhelper python script are you referring to?
