1. there is an internet tab configurator that you can find on xda that will copy your PIE links to the M2D start page.
2. Want a nicer calendar interface? use the free version of thumbcal (0.51, I think) and apply the quick fix for linking it as your default calendar found in the original m2d thread on xda linked above.
3. M2D is hard coded, and simply adapted for use on other phones - it is not simple to make most of the changes you listed. It has taken multiple developers (many thanks to mpenguin14, herg, and many others) a lot of time to get it to where it is now, just to make it work on our phone and others. Eventually, further options and other ways to configure it will be figured out, but understanding how we got M2D and what it took to get where we are should temper complaints about it. It is what it is because of the way it is hard coded, and to alter that takes time and work. If you want to see things change, the place to post your thoughts is over at xda devel where it is being developed, in the main M2D thread, and in the M2DC thread, with the understanding that there is a significant amount of time and effort being placed into development by good-willed developers, and that there are many more bugs and issues to address besides your wish list. Better yet, since you have wishes, learn some code, and develop a tool for us all to implement your changes - this is what other people who want to see changes have done. Then you might appreciate what it takes to make such changes.
