## GENERAL

    * Face matching:
        - upgrade to face distance per face per file
            - so we dont get 2 x same face in one file, and if it could match say Cam and Mich for 1 face, take the higher match, not the first one to be over the threshold
        - allow for threshold/settings to be tweaked from the GUI?
            ---> at least settings for default value (back to 0.6 / 0.5?)
            ---> with override table to do per file / per face?
        - face locations:
            START FORM SCRATCH so all images have face_locn data
        - algo:
            for each face (even known) in image
                foreach refimg
                    get face_distance
            sort by face_distance
            for each face
                connect lowest score with that face (for this file)
                this means this face is no longer 'free' for a match
                if (sorted) face distance > 0.55 stop as no further 'matches'
        - use cnn model (check ftst.py) for ref images, and potentially as a setting to check images without a face?
        - or always?
            -- would CUDA be useful here? (which is faster say an old 730 or the AMD cpu?)

    

    * viewer:
        can we make it preload next/prev images, and only reload the image div when we jump?  to make arrow-based nav much faster

    * remove dirs after the duplicate cleanup removes all its content

    * could look to remove the hand fixing of json.loads of array data --> seems you can make your own datatype in the ORM, and it can do the conversion every time you use it

    * fix up logging in general
    * comment your code
    * more OO goodness :)

## DB	
    * Dir can have date in the DB, so we can do Oldest/Newest dirs in Folder view

### BACKEND
    * revisit SymlinkName() and make it simpler (see comment in shared.py)
    * if you change paths in settings, then re-run Initialisation checks (for symlinks to new path names)
        - this actively is crashing, added a file in storage2/ (no symlink), so job mgr crashed, and DB doesnt have the content until you make the symlink (via re-running job mgr)
    -- started on some basic optimisations (commit logs every 100 logs, not each log)
        - with debugs: import = 04:11, getfiledetails== 0:35:35
        - without debugs: import == 04:03, getfiledetails == 0:35:36 -- not a sig diff
        - with exifread & debug: import == 04:26

    *** Need to use thread-safe sessions per Thread, half-assed version did not work

    need a manual button to restart a job in the GUI, 
        (based on file-level optims, just run the job as new and it will optim over already done parts and continue)

    Future:
        Admin
            -> reset face_flag

        AI
            -> rescan <dir> for <person> --> can do this on new image only
            (optimised to only scan has_unidentified_face)... BUT if you change
            thresholds on AI, or we get a new/better one some day, then it can
            all images with faces, or if we 'reset face_flag' rescan all images

        Admin
            -> delete old jobs / auto delete jobs older than ???
            -> do I want to have admin roles/users?

### UI
    ??? ipads can't do selections and contextMenus, do I want to re-factor to cater for this?

    file details is sort of crap - only works on import path
        - probably better to have a different 'view', e.g. folders/flat/detailed

    job management:
        joblog needs to show only say 25 log lines (last?) by default and allow see start/end, page by page, and search
        clear all jobs (via GUI)
        clear old jobs? (via b/end?)
        clear FE messages (at least dup ones on File data deletion) -- in backend
	need to copy into here the jquery/fa files so we don't need internet to function
        - for that matter run lightspeed against all this

        timelineview? (I think maybe sunburst for large amounts of files, then maybe something more timeline-series for drilling in?)
            (vertical timeline, date has thumbnails (small) horizontally along
            a page, etc.?

### SORTER
	* exif processing?
		* location stuff - test a new photo from my camera out
        -- image is in dir, need to look at exifread output

### FUTURE:
    * can emby use nfo for images (for AI/tags?)
        -NO sadly
