If not displayed, you might need to adjust the vertical boundary to the right. You can also change the position by going to the plug-in properties. To go to Properties, you can right-click on the Search button on the Plug-ins toolbar, and then select Properties. You can also select Plug-ins, Customize Plug-ins on the Tools menu, select Search from the list, and click Properties.
Okay, besides the line number, I’d prefer the whole line, which contains the matched string, be displayed. This would give you an additional information on match (without a need of jumping between line just for seeing the line contents).

What do you think about changes in this plugin?
