Better File Selection for Many Files (and FileExplorer issue

[librooks]

If I have more than, say, 50 html files open in RapidCSS, trying to select the files that are not in the active dropdown list on the right requires me to click the down arrow at the bottom of the list and keep scrolling until I find the file I want, which takes forever if I have 100 files open. The list should be scrollable. Notepad++ has a Document List feature that works perfectly. RapidCSS does have the FileExplorer feature, but it doesn't open the project I'm currently working on the way Notepad++ does. Instead, it opens the last project I was working on. If it opened the current project automatically, that would be great.
