Group buckets when assigning a transaction to a bucket

[StephanieLemoine]

Now you get a long list of all bucket. Which is difficult to search in when you have many buckets. You might also have similarly named buckets in different groups.
It would be helpful if the group name was also visible + if the buckets are sorted and grouped per bucket group.

I've made a change to the upcoming version that will append the group name to all buckets with identical names, like "Bucket 1" in this image:

I know this isn't exactly what was requested here, but I'm not quite sure how to best group by bucket and allow for fuzzy searching. For instance, if I have this scenario:

• Group 1
  • Chocolate
  • CACP
• Group 2
  • CC Payment

If I type "cc", with fuzzy searching enabled and without grouping it would rank matches as:

• CC Payment
• CACP
• Chocolate

If buckets are grouped, it would likely be displayed as:

• Group 2
  • CC Payment
• Group 1
  • CACP
  • Chocolate

However, how do I handle the case where different groups have different ranked results? For instance, if Group A has the 1st and 4th best matches, Group B has the 2nd and 5th best matches and Group C has the 3rd best match, do I show Group A first even though it would but the 4th best option above the 2nd and 3rd?
