I do not know whether the below it is a solution and/or whether it is feasable at all.
Just an idea...
But what about (optionally
!) splitting the clipboard, say in monthly or quarterly clips,
or volume based split?
Or split into:
-Recent  Months (e.g. keep clips upto 2 months)
-Old  Months (e.g. keep clips upto 12 months)
-Archive (clips older than 12 months)
-by default search recent
-if nothing is found, user can TAG search in 'old/archive' clips as well, which may take longer.
Well, I don't know, these are just 'wild ideas' ..
keep up the good work!
p.s. with 'copy to clipboard', in my earlier post, I mean this button
vainly tried to upload the video here, so you cud play it without.. downloading.
regretfully this is not possible, without using youtube.
therefore you need to download it first now.
