Just in case someone is interested in having simple visuals for SMS, Call and E-mail that don't stand out too much:

PatternCommunicationEmail=30;1;0;bR;9d8002ff03ff02 ff03ffe00440007f00e1000000;9d80e08002ff09ff7f007f0 07f00e00240000000


All have two fast blue flashes (like normal info on those) plus distinctive colour for each - this makes it easy to tell if there is just e-mail or important sms/call that requires attention. Nice to have on meetings where unnecessary juggling with phone is awkward.

E-mail is blueblue-red
SMS blueblue-"yellow"
Call is blueblue-red

Alter colours as you find appropriate.

edit: Some odd spaces in the middle, remove all.
