In Spark's source there is spark_i18n_ky.properties file which i don't know what language it is made for and it is not shown in the GUI as a selection of an available language. Maybe it was named wrong and should be not ky, but something else. Or maybe we can just remove it.
This wasn't on the gsoc-teaser list btw
Then weird, because it shows for me it is on gsoc teaser list. It's Kyrgyz language, but I am still going to investigate showing it in GUI. But first I am going to finish Spark-939.
gsoc-teaser label search shows 72 results right now and i don't see this one on the list. Anyway. If you wish, you can tackle this, but this is a very minor thing.
The side panel shows the whole list of issues for Spark project (272 in total). Not sure why it does that. The ticket itself doesn't have a gsoc-teaser label in the Labels field, so you can use that field to make sure if a ticket is gsoc-teaser actually.
