Better use of browser real-estate?

[CV-GPhL]

Would it be possible to enlarge the used area for

• the main overview page: it seems to be hard-wired to use only 83.333% of the width with empty grey areas to the left and right
• the "View" pop-up window (which is both limited and fixed in width/height): it could easily use more width

Much better for the View pop-up windows would be if it allowed re-sizing when encountering HTML files (while starting from the current size to have a sensible initial default). I find the strict and enforced fixedwidth property rather limiting and odd in the context of looking at a HTML file.
