Currently jEdit will fold code like...

    sub x() {
        yadda yadda
    }
    sub y() {
        yadda yadda
    }

...as...

    sub x() {
    }
    sub y() {
    }

jEdit should fold in any lines that only contain whitespace and one "}", so twice as much important code is displayed per screen, e.g.

    sub x() {
    sub y() {

Perhaps have it as an option, in case anyone prefers seeing those singleton }'s. My current workaround is to indent those visible }'s an extra space, which is a pain.
