The only thing I'm not sure that I changed the code everywhere. See, please, so that there are no extra lines that are no longer needed at this implementation. For example, these lines are confused me: https://github.com/shirsig/aux-addon/blob/30c39e1d2f528e14c84d1621c1a6ef50e33b04a4/util/filter.lua#L335-L337 and https://github.com/shirsig/aux-addon/blob/30c39e1d2f528e14c84d1621c1a6ef50e33b04a4/util/filter.lua#L367-L369 It seems to me that since the operators are added to the filter_util.filters table, it is no longer necessary to add separately in suggestions table, but I'm not sure about it.

oops, sorry, I forgot to delete my localization code

I came up with how to save the order of displaying filters and even set and change it at any desired moment. I will make a commit a little later.

Done :-)
