Freron MailMate

I use a gmail imap account in MailMate (Version 1.13.2 (5673)) on my Macbook. When I attempt to perform multiple simultaneous tagging actions, the tags, or a subset of them, are lost.
For example,
- if I select multiple messages and add some tag to those messages, and remove a tag from all those messages using the tagging interface (T shortcut), the remove operation does not perform. - if I attempt to remove and add tags from a single message, it works as expected - if I define a keyboard shortcut to remove and tag and add one tag, the result is inconsistent. For example, if I want to make mutually exclusive tags of 'save' and 'to_delete', I want to use a shortcut that tags a message as 'to_delete' and at the same time remove any pre-existing 'save' tag. The outcome of such an action is inconsistent, i.e. sometimes both actions perform, but most of the times, the 'to_delete' tag is added but the 'save' tag is not removed.

I think this is happening because MailMate attempts to sync with the Gmail server before the user enters all the tagging actions, and only a subset of the tags get synced with the Gmail server as a result, the ones that the user entered before MailMate attempted the sync.

A potential fix could be to initiate sync only after all tagging requests are complete. For example, in case of the mutually exclusive tagging example above, I am listing two tagging actions in my shortcut, but MailMate probably starts syncing with Gmail immediately after the first action. Instead, if MailMate did not sync by default after the first tagging actions and instead an explicit sync action was available, I would add the sync step after all the tagging steps in my shortcut command.
