All palette tags seem to be lowercase, yet you can search with uppercase letters and not be shown any results, even if you've otherwise matched a tag exactly. I believe it would be a small but impactful improvement to mobile user experience to ignore capitalization in tag searches. Of course, once you know about this, it's easy to work around, but without prior knowledge it can be quite confusing and frustrating. Mobile keyboards often auto-capitalize the first letter, and it can seem like none of the tags your searching for exist, or something is broken.
