Hi Michael,
Thank you for your kind words, again!
2. Well the category and tag filters are actually separate, so I am not exactly sure, you might be reffering to something else here. I mean the filter by tags option, which is a differnt option from the category filters: https://i.imgur.com/Yrrh45Q.png
4-5. That is exactly what I am going to do, include it as a separate element within the content type filters. (as it should have been there arleady)
Post format in titles
I might be able to modify the previous code to include that in the titles as well. Let me know, if you are interested in that.
New Bug Related to the No Results Container
That is a very rare issue, I have actually investigated and fixed some instances of it before. It happens, when the predicted number of results is not accurate, and the plugin tries to load more – but instead it gets the no-results box.
The inaccuracy is usually due to a custom code, that may affect the results count after the search is finished. I don’t recall if I suggested anything similar to you before. But if there was any custom code that may alter the number of results in any way, that I suggested, then that would explain it.
I have noted this as an issue, and I think I know a way to fix it once and for all. Expect a bugfix for this in the upcoming release.
