[MlMt] MailMate status (All things HTML)

[Benny Kjær Nielsen]

Hi again,

here is another one of those cutting edge 
[downloads](http://updates.mailmate-app.com/archives/MailMate_r5110.tbz) 
(r5110). It fixes a few issues including a major problem with the 
settings for the Spotlight support.

Speaking of Spotlight. BusyContacts 1.0.4 has been 
[released](https://support.busymac.com/blog/59968-busycontacts-1-0-4) 
and the BusyMac people have been so kind as to implement support for 
MailMate (via Spotlight). This means that MailMate emails related to the 
currently selected contact is listed directly in the BusyContacts 
interface. This should also work with the beta of MailMate. In other 
words, you don't need the cutting edge version I linked to above.

>> 	git clone https://github.com/mailmate/asciimath.mmBundle

>> 	defaults write com.freron.MailMate MmBundleCommandForMathStyling 
>> -string A5574670-971A-47B4-86F8-A2901F252613
