Apologies if this info has been posted elsewhere – I searched but couldn't find it.
I'm a former user of Knoppix v5.1.1 and v5.3.1, I've been forced onto v6.2 because older versions won't boot on my new PC.
There are a number of things I don't much like about this new version, and I'm wondering if I can configure them back to the way I prefer.

Rapid movement of mouse across Desktop can cause a set of small windows to appear – it looks like some kind of alternate Desktop feature, can I suppress this feature?

Slow Window Closing - a fancy feature where the window breaks up into fragments before disappearing. Sorry, but it's just annoying when I'm in a hurry.

No Partition Icons on Desktop. I found the icons when I opened PCMan File Manager, but the partitions then mounted in read-write mode, which I don't necessarily want. In v5 I could click the desktop icons to get read-only access, or click Home button on Taskbar followed by Go > Storage Media to open partitions for writing to.

There seems to be no General Help, I can only find help for individual apps.

Sorry if I sound a bit grumpy, there are some things I like as well
