There is an issue with Lightroom keywords not remembering the last keyword used when typing in the Library/Loupe module. In previous versions, if I typed a keyword and then auto-advanced to the next photo (using the filter of "none" for keyword), the next time I started to type a keyword with the same first letter, it would auto-populate that last keyword I typed. Now it just pre-populates with the first in alphabetical order. I have two hockey players named Zac and Zach, and Zac comes first in alpha order. It is very time-consuming to have to type all four letters of Zach's name when I have 6 or 7 pictures of him in a row and it SHOULD remember him after the first picture and therefore come up immediately when I type the letter Z. I tag hundreds of pictures of hockey players in a season and this is a HUGE time waster for me. I am now on 8.4.1 release, and in my previous version, it worked fine.
