Kcbedo over at XDA managed to tweak the HTC Browser for Android so that you can have 16 webpages open instead of 4 (something that personally bothered me about the browser). With the help of TomLeeDesire, he was able to tweak the apk file for the browser and then repackage it.
Simply head to his original post here and read his first post on how to install it. Please keep in mind though that this will only work on HTC devices with HTC Sense running on them.
If you like the tweak, please let the developer know by thanking them and/or donating to them.
