Is there any way to force it to keep the assets for open tabs in the web page cache? If I have a few tabs open I should be able leave the browser, run enough stuff (take a call, play a game, text) to force the browser code to flush from memory, and come back and view the pages I have open without having to endure ANY reloading. This seems to be a problem with all the android browsers I've tried.
