[OTR-dev] OTR encryption state

[Greg Troxel]

  i totally agree with that, but it may be worth the work. i'm not sure.
  it depends on what people think will be best for the user. someone
  else weigh the cost/benefit ratio here between code
  complexity/portability vs UI enchancement. =)

I consider it a serious bug that I can't check a box in otr prefs to
say "don't try to do otr with this person for now".  Right now I have
to delete the fingerprint to get that effect, and that opens me up to
reverification issues.
