The preset file is in C:\Program Files\Purr Data\bin\css folder (on windows 10)

I was able to drag solarized_inverted.css onto the desktop and edit ,box_text to #ff6600 save and drag back to the css folder for the following result.

I personally wouldn't recommend this approach as I would imagine when updating Purr Data the .css file will be overwritten and possibly updated with new fields

I tried to make the purrdata folder read/writeable but it just kept reverting back to read-only

I think you may need to use a message box to this, I dont believe you can put a comma in a list box
use messages with add2 and addcomma commands

I thought I would have a go
maybe this might help

To change the contents of a message box, use the 'set' message

You could write the values via a sinesum message to an array

Another way when patches disappear off screen on windows 10, is to hover over the Pd icon on the task bar and right click on the missing patch's large icon title bar then click maximize, then drag down the maximized title bar to restore its size.
The missing patch appears as a blank patch on the task bar icon.

I think [list split] is what you need

Another possible choice is to use [makenote] instead of [pipe], although 1 millisecond needed to be added to the bang delay.

@esaruoho I sent this while you were replying and might of skipped it

the bang between [r $1-id] and [array get plom$1] looks like it is blocking the id, and the delay is toggling the metro twice
