In the very old version, TB already have Tags for mails. And For the 1st 10 Tags in setting, it will default set to using 0 to 9 for quick tags. However, the setting of tags cannot be sorting by manual. If we need to re-sort the Tags for quick input, we can only delete the old one and add. But what if more than 15 tags? It is nightmare. Till to TB 68. I use Tags Toolbar add-on to simplify the using. But it cannot since TB 78. Only pulldown menu. It is very not user friendly interface but tags was and very advance data management concepts (Starting by Gmail). Hope there is some easy way to setting the sequence of Tags, or tags management. Thanks.
