I've been using LastPass for quite a while, and have loved the Android support. However, I too must ask that we be given the ability to completely, 100%, absolutely disable the browser functionality within LastPass for Android. Even though I have my default browsers all set, and finally get to the point where I'm no longer being asked if I want to use LastPass to open links, whenever I directly open LastPass from my app drawer, the first thing it does is try to show the LastPass browser's home page.
Hint: If I'm opening the LastPass app, it's to login and wake it up because it didn't automatically detect the password field in whatever app or website I was just in. It is not because I want to torture myself with a completely different browser that lacks any of my bookmarks, preferences, or cookies. All I want is for LastPass to open to the login dialog, and as soon as I login, go straight to my Vault. Not the browser.
Please, give us the option to completely disable the browser feature in LastPass for Android.
