Very long period filter

Hello to everybody,
I just learned about this wonderful tool and started to use it. Looks very powerful!!!

I would like to apply very long period filters to my data, e.g. filtering between 100 and 1000s
(.01 and .001 Hz) but I am not allowed to insert more than 2 decimal places and .001 can not be inserted.
I searched the source code but could not find the place.
Can anybody suggest me the best way to do what I want?

Thanks

There are gui tricks to increase and decrease the number of digits in value spin boxes.

Spin boxes accept the following actions (combinations of mouse wheel button and modifier keys):
- wheel button alone: increase or decrease the value
- CTRL(COMMAND under Mac)+wheel button: increase or decrease the value with a bigger step
- ALT+wheel button: increase or decrease the number of decimals (precisely what you needed)
- SHIFT+wheel button: increase or decrease the step by a factor 10.

Hope this helps.
