Please, How are filters organized in the library to be shown first?

On the filters library page

Filters Library

You can easily know how filters are shown on these two tabs

RECENT : They are organized correctly by submission date

POPULAR: These are organized by their popularity and number of download on the current date so it changes according to the evolution of the popularity on each day

But then all the others options is not clear and known HOW are filters organized in the library to be shown first ?

FEATURED ----------------------------------------------

Does it appear them at random each time you refresh the main page ?
Because each time you refresh the page they are organized totally different each time

BUT curiously this is not true if you go to see ALL the featured filters list, they are NOT organized at random and it will show always the same ones on the first page

Featured 8 pages of filters - what filters are shown on first page?

ALL FILTERS BY CATEGORY ----------------------------------------------

If you go to the categories list it seems that they are organized in some fixed kind of way, but I do not know what is used to organize them and which filtewrs are shown on the first places and first page

For example MISC category - what filters are shown on first page?

AUTHOR PAGES ----------------------------------------------

If you go to an author page to see all the filters created and available, is also not known what filters are shown first and why

Ramlyn 9 pages of filters - what filters are shown on first page?

"CUSTOM SEARCH" ----------------------------------------------

If you make a custom search for a any keywords used, what filters are appearing first in the search list?

Is it organized by relevance and matching first the filters that contain the keywords we have put on the search?

Custom search example for filters that have lines

Thanks very much for your help

This has alreaady 1164 views and is still not answered, so I think that many FF users wants to know about this too.

Thanks for your answer GMM, so iif filter catgories are sorted by popularity, then are also the author pages sorted in the same way, by popularity?

Please GMM could you please, confirm that they are sorted all by populariity except the ones that are by date ?

I think that sorted by popularity means how many times this filter has been downloaded and not how much it is used.

This would explain why it is changing and why they are new filters mixed with very old filters at start

Thanks very much
