For those of you who want to give some extra behaviour to the browser key on the dock, here's one solution.
Although mod Aroma "kind of" does this, it should be noted that this solution is easier to recover from.
The browser key launchs any apk with ˋcom.android.browser.BrowserActivity´ as main activity, so I made a small app that mimics that.
It gathers a list of installed browsers and prompts a choice to the user; With the help of intents.
You can build it directly within the prime using AIDE, as it was coded in it.
GitHub repository: github.com/bit2shift/BrowserShortcut
In order to install it, you first need to remove the stock browser. Use Titanium Backup or ES File Explorer.
Install the replacement app as usually.
A screenshot of its choice prompt is attached.
EDIT: The google homepage is the URL used to query the installed browsers and start the chosen one. You can change it to something else.
TIP: For some browsers, about:blank does not get recognized properly.
