A few questions/comments.
1) Is there a good clean solution to combining the various split profiles of identical actresses? I.e., when I find a profile of an actress with the name of, say, X-Woman, but her real name is A-Woman, and Javluv won't simply let me rename X-woman as A-woman, because "A profile with that name already exists". So the only means to combine the profiles is to search both profiles in actress view and carefully CTRL-select just the two correct profiles, even though they are separated by hundreds of profiles and dozens of page scrolls apart. Is there an easier way to combine split/misnamed profiles?
Probably the easiest way is to use OR in the search bar. If you type "A-Woman" OR "X-woman" in the search bar, both will show up in the search. It's then easier to CTRL-click and merge them. I realized this was a problem a while ago, so this was a big motivator in adding "or" support to search.
2) Couldn't we just avoid this problem entirely by using databases that don't use nonsensical and clearly faulty names for actresses? I use JavLibrary as my main online database and I never see ridiculous names like "Even One Color" for an actress. Maybe put a user-switchable option in settings as to what database gets accessed for a specific types of info? I would certainly choose JavLibrary as my sole database for actress names. Perhaps I am oversimplifying this and there are technical aspects I am not taking into account, of course.
JavLuv does, in fact, use JavLibrary as it's primary source for actress information. But unfortunately, there are still a lot of actresses who don't have an entry there (or an incomplete entry), and so JavLuv falls back to other databases. The problem is exacerbated if the movies you scrape don't have entries at JavLibrary either, which again, is pretty common for more specialty, obscure, or older movies.
There's also the problem, of course, that we're working with imperfect English translations to begin with. Even with someone famous like Hibiki Ootsuki, there are literally no less than three ways to spell her last name in English, and none of them is more technically "correct" than another. Add to that the myriad alt names actresses have, many of which are poorly documented, and it's not an easy problem to deal with.
JavLuv does the best it can, but at the end of the day, I'm afraid at the moment we have to rely on the user to disambiguate a lot of this conflicting info.
3) Will integration into online databases ever be implemented? I am very much looking forward to a time when Javluv can log into my Javlibrary account and mark all of my collected movies as "I've got it".
Probably eventually, but don't count on it soon. It's on the wanted list list, and I'd like to get to it someday, but as always, I make no promises about if or when new features are implemented.
