Windows 7 - discussion and advices request

Hello.
For a couple of days I got Windows 7, I haven't got too much time to tickle it to be honest but I browsed the features (most - visual ones) already made an opinion, as I assumed there are no other hidden/unintuitive settings. Generally I liked it, it was as I expected it to be with a few exceptions which I intend to change to fit my needs. I'd split the features into 4 categories:
A. present in XP/Vista but not in 7 (discontinued)
B. present both in XP and 7 (continued)
C. present in 7 but not in XP (new)
D. not present in either (wished)
From these I'm interested in A. and D.
A. I wonder why do they discontinue things or make them worse?
1. toolbar docking
In XP you could dock toolbars either to the left. right, bottom and up, separately; I may not find the setting but I think it's impossible with 7.
2. My Computer pinned
This is too much! I have to go through WE to get to My Computer or Network. I found a tutorial on this forum on how to solve this so it's done.
3. Sticky Notes gadget
This is very controversial so I won't debate. I just want it as close at hand as it could be. If it were by me, I'd have an digital notebook just by the mouse. So I want the gadget. I don't want to put the application in startup folder and hide the taskbar button. It's lame. If this is not fit to be a gadget, no other tools are. Not to mention clock (already in systray) or pictures... I found this too (a modification)
D. Do you think these can be achieved somehow?:
1. icon grouping
Even from Windows 98 I felt the need to have the icons on the desktop grouped, so when I rearrange the icons by type/name, they wouldn't shuffle (they in fact are shuffled by my criteria). I was (still am) working on different projects and I used to have a background that looked as if there were icon groups, as for each project I have several icons.
In my vision, you could arrange icons in each group separately and the default commands in background right click pop up menu would be related to groups.
2. enhanced desktop
"I want" is too little to say; "I need" is more proper to say. So, I need more space for desktop. You know that version of Linux with 2.5D-like desktop? What do you say about it? Or at least to make it scrollable so when you click (or just hover it if more convenient) a desktop zone in the right side, like "show desktop", in fact a border just continuing the "show desktop", to slide to the next desktop. More than 2 desktops would be cumbersome. The idea is to not overdo with desktops at the expense of ergonomy. If the scroll bar is an issue for those who doesn't have a scroll mouse, make it to the left side.
Or just put 2 buttons in the taskbar near the language one, each for a desktop.
Or put them in a gadget.
3. a little file handling
If in an 154 files copying process one cannot be copied, the whole process is aborted. This issue is frustrating and lasts for decades. When will it be abolished?
After all, Windows is a system not a programmes suite.
These buttons please:
'No to all'
'Skip' // when a file is corrupted or too large, the user can skip it from copying/moving.
'Update' // overwrite only older files.
'Pop'/'Unpack' // on folder: all contained folders and files are got out of the folder, one level up and the empty folder deleted. This is important as it's cumbersome to handle two nested folders with the same name.
'Flatten' // on folder: all contained folders are popped; so, in the current folder there are the files in all subsequent levels (folders) and only those, not any folder.
