Right now it looks like the worst of what could be done by a 1st year in programming student ...
Proposal :
1st line for a readable LL warning = "Load web page ?"
(empty line)
2nd line for scripter = URL
(empty line)
3rd line for scripter = optional string message
(empty line)
4th line = as it is now with the "From Object etc."
Correctly adjusted on the left and avoiding a "?" that is for now floating at the end of the url will make it look better ... and such a simple modification takes 2 mins to be done.
