I've been playing with this neat button you created Kenneth and I must say it works fantastic!! 
No lag or whatsoever in the script. Excellent..
This is worth posting in the Buttons & toolbar section. Especially if you assign the main button's command to Ctrl + double click it's a real time saver.
tnx again.
Another question: Let's say I've organized 10 photos orderly. Later on I find another photo that should be somewhere between. If I were to squeeze one photo into the sequence and the photo should be nr. 5 Then I do this:
[ol][li]Temporarily rename '5 up and till 10' to temp...[/li]
[li]Delete existing sequence data[/li]
[li]Initialize new sequence data[/li]
[li]Enter sequence name. Starting position = 5 and go[/li]
[li]Then select the temp-files and go[/li][/ol]
Is there a quick way to do this..Kenneth since you wrote the script, maybe you could add this to the button group.
PS: I'm not being lazy. I just love to see possibilities being pushed to the limits of Opus
