Sugestions for plugin

[expertup]

I have some sugestions for pulgin:

1. I think that good idea is attach list with test codebar scanners. I have Zebra LS2208 and I can make test on them. This programmable scanner and I can set many options

2. You can detect delay between keypress. Scanners have very short delay in comparison to human key press delay. For example if delay between key press is short than 100ms, that mean codebar scanner is "writing" text. But if any delay is longer than 100ms that mean is human text writing.

3. Some codebar scanners have as end char tab key, key code 9. You have detect only Enter key in Your code (Enter is 13). But sometimes as Enter is used char code 10. Maybe good options will be add settings end char or include more char codes.
