Sorry if we didn't satisfy your all requests. I guess you forgot

It's annoying to have to wait for a long time in this case, but we're not
ready to spend many efforts on that. Any external contribution is welcome
here.

I'm not sure it's so simple, but this should be considered.

These tables are well displayed

I see not indication in the HTML 4.0 recommendation that says that
it's incorrect.

I don't see what is wrong in Amaya.

We don't plan to add complex algorithms here. The table formatter is enough
slow today.

This is in the todo list.

What is wrong?

This is in the todo list.

I'm not sure it's still true.

It would be better to do that but that takes time.

People asked the full list of what CSS rules Amaya doesn't support.
It would be helpful for us if you can provide that list.
We try to progress in each release, but it's a long long way.

> Editor Problems

I did you start with edit mode off?

> E2] Shft-End and Shft-Home do not highlight text for cut/copy operation.

Word selection was added, but not Shft-End and Shft-Home.

> E3] Shift-DownArrow includes first character of next line in highlight
>     when it should not do so.

It's considered as an extension to that last character, so the last character
in included.

No idea of what is the problem.

That occurs sometimes.

> U3] The scroll bars can't be pulled to the very bottom or right edge.
>     No information is lost but this is untidy.

We keep a space at the bottom of pages.

I tested on a document and it worked well. It should occur in
specific cases.

> Keyboard Shortcuts
> K1] Standard shortcut nomenclature should be used in menus.

>     Ctrl + Enter  instead of Ctrl Return.

No because Amaya needs a lot of shortcuts and so interprets differently
Alt P and Alt p. Amaya also accepts sequences of two shortcuts. It's not 
because Windows applications are limited that we should maintain the
limitation.

> Compose Function
> C1] Creating a soft hyphen adds a &173; to the document which

Amaya doesn't generate a &173;

This is in the todo list but with a low priority.
