Yes, I notice that when creating a task, if I start to type the first letters of an existing tag (e.g. 'Wo' for 'Work') the 'Work' tag in the bottom of tag chooser/tag cloud will be bolded which makes it easier to select (even though pressing enter doesn't really autocomplete and select it like it should) the other tags remain visible instead of being filtered out, which is weird.

Also if I then click on the bolded tag it will appear as chosen at the top, but the letters I've typed in the text field remain there instead of disappearing as they would in almost all other software I've used. The tag functionality seems to have gone backwards for some reason. Very frustrating.

EDIT: I've just noticed that the tag chooser does have autocomplete tag functionality, but it's obscure and unintuitive. When you start typing a word such as "bu..." if you hit the tab key it will autocomplete to 'business' however there's not highlighting or indication that this is occurring or that it's even an option, and no tags are suggested.

Also If I have more than one tag starting with B, for example 'Business' and 'Buy' it just autocompletes 'Business" there's no way to change to select other tags. Ideally I would like it to suggest a tag based upon my initial typing and then I can press tab repeatedly (or arrow keys, better to have both options) and then space (or enter, better to have both) to select the suggested tag.

It is incredibly frustrating to not have this functionality which is standard in almost every other software and it's a real productivity killer.

type ahead will likely be a little quicker than searching and clicking.

Typeahead function will prevent setting duplicate tags due to spelling error.
