## GENERAL

    * allow rotate of image (permanently on FS, so its right everywhere)

    * improve photo browser -> view file, rather than just allowing browser to show image

    * need AI code to:
        - make use of new FACE structures/links ... (code for this is in pa_job_manager, just not being called/used as yet) && something like:
        FindUnknownFacesInFile()
        MatchRefImgWithUnknownFace()
        Then create wrapper funcs:
            MatchPersonWithFile()
                for each ref img for person
                    MatchRefImgWithUnknownFace()

            MatchPersonInDir()
                for each file in Dir:
                    MatchPersonWithFile()

    * then in UI:
        allow right-click folders in folder view (at least for AI scan) for all files in Dir
        allow right-click AI
            for all persons
            for individuals
        (and can be on an individual file or an individual dir, or selected files / selected dir)
         
    * fix up logging in general
    * comment your code
    * more OO goodness :)

## DB	
    * Need to think about...
        file (image) -> has X faces, Y matches
            X == Y (optim: dont scan again)
            say X-Y == 1, then to optimise, we need to only check the missing
            face... at the moment, the DB structure is not that clever...
            (file_refimg_link --> file_refimg_link needs a face_num?)

    * 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

    - would it be quicker/smarter to use md5 hash matching on import (and if
      so, not re-do face* ) ???

    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.?

        https://www.highcharts.com/demo/packed-bubble-split

### AI
    * allow for threshold/settings to be tweaked from the GUI
        - it would be good to then say, just run the scanner against this image or maybe this DIR, to see how it IDs ppl


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