Once you decide that you support finger use, you need to change your paradigm from desktop applications to mobile applications. They will be "less powerful" in terms of not having the breadth (and the depth) of their desktop counterparts, but they will be more powerful and more usable in the selected mobile use cases than simply trying to utilize the desktop UI into a small device.

It's like Henry Ford, but in the opposite direction: We have a desktop application, a horse. Trying to maintain the current desktop/stylus UI's as such is as like breeding smaller horses. Yes, you can perhaps breed a small horse, and it might superficially look cute on a small screen, but using it reminds you all the time, and rather painfully, that it's ultimately a crappy experience compared "to the real thing". It's not a strong or fast or easy to ride.

Trying to compete with desktop computing on its terms will fail. The devices have small screens, cramped input methods, less power, less storage etc, poor mouse adaptation etc.

Mobile devices need mobile UI's, taking use of the strong suits of the device, instead of trying to emulate the strong suits of the desktop environment. You need to create dogs (or choose the useful pet of your personal preference), not smaller horses.
