It would be most excellent if I could click directly into the "Enter Expression Here" dialog to start editting my custom filter, rather than having to click the "Custom Filter" radio button.
For me it typically requires three clicks to get going. I often start with a "Basic filter" then:
1) Click into "Enter Expression Here" dialog and nothing happens.
2) Remeber that I need to click the "Custom Filter" radio button.
3) Click back in the "Enter Expression Here" dialog to put my cursor where I want it.
Thanks!
