Hi,
I like to highlight text when I read web clippings on DEVONthink for Mac, but sadly DEVONthink To Go doesn’t seem to allow me to highlight on web archives. Would there be any plan to update on the next version?
on the next version?
Not on the next maintenance release, no. This is not a trivial thing as it involves the internal text engine. This may be a feature of the next major release, but no I can’t give out any timeframes on that. Thanks for your patience and understanding.
You’re welcome 
3.0 has launched, but It still not that feature, so sad.
maybe 4.0?
It depends on what we can find in a replacement text editor as this would fall under rich text editing.
