Version:           0.8.2 (using 4.2.2 (KDE 4.2.2), Kubuntu packages)
Compiler:          cc
OS:                Linux (i686) release 2.6.28-17-generic

How to reproduce:

When using the Review Tools (Tools, Review), the highlighter tools all have opacity 100%, which makes them not be highlighters at all. Additionally, they are too narrow. It is possible to change the opacity and the width after applying the tool to a document, but Okular does not remember those changes. When using the tool again, even in the same session, opacity is reverted back to 100%.

Expected behavior:

Highlighters should have opacity much less than 100% (maybe 50%)?

Suggested fix:

The immediate fix is to replace 100% with 50% in the code. A better fix, to add a configurable opacity setting at least in a file under .kde/share/config, or to document that feature if it exists. A true fix is for a right click on the tool button itself to bring up a dialog where the settings can be changed, then to make those changes persistent.

By the way, in an unrelated note, I tried browsing the source for Okular online and couldn't find how, other than downloading the package.
