File Location information and locking film strip

Just a couple of issues requiring attention (plenty more that have already been mentioned):

1. I use external drives and network drives almost exclusively for image storage (limited HDD storage on laptop), and so it is not uncommon for a drive to be unplugged, or for file directories to have been moved when L3 is opened. 
If the files were added in the DAM as a Folder, then L3 shows empty thumbnails with little exclamation mark in a triangle which allows you to either locate the folder/file or remove it from the catalog. That is fine, except that there is no indication of where the files originally were or where L3 thinks they are. And if you get it wrong then you lose all your edits etc.

So we need to have information about a folder or a files location, not only when the file's location is known by L3 (you use "show in Finder"), but when L3 cant find the location. There is no way to know (at least easily) the reason why a folder has not been found. 

If folders or files are moved from within L3 it knows where the new location is... but the problem is that using L3 as a file manager from a laptop, back to files on a server, across a network is a recipe for problems.

This problem could also be lightened by having .xmp side car files to hold edit information, and having the ability to say as .lmnr files. I only save edit info when I don't complete editing in one session. 

2. Need to be able to lock an image when it is being edited, as quite often the slightest wrong movement of the mouse can cause you to move to the next file or two. This is the impact of having the film strip feature, which remains active when if hidden. This feature should be optional...allow us to turn it off, as it is very annoying when the image being edited suddenly changes.

All in all a few of the many reasons not to want to use the DAM with L3....

Be warned that if you only use the quick edit feature then if you have these stored on an external drive, and don't have the drive plugged in when L3 is started then these files disappear from the DAM and can only be restored again from a backup. They don't reappear when the drive is plugged back in again.

Hope this makes sense ... a bit rambling I know, but hopefully gets the point across.
