Thunderbird 24 issues
A mildly annoying issue is that if I change the settings on todist.com (such as the start page), or upgrading to premium, I have to shutdown Thunderbird and reboot my Windows 7 PC before the Thunderbird todoist plugin recognizes the changes. Syncing, closing and reopening Thunderbird, or logging out of todist and logging back in do not help. (I don't anticipate changing the settings, now that it is setup.)
More importantly, when adding a task from an email, if I select the email from a list, todist adds the email which is FIRST in the list, not the email I selected. I have to actually open that email from the email list to get todist to select it correctly.
