You misunderstood me. I just speak about what the connection feature offer
directly. It offers read-only access to calc comaptible files (including
text files). It is other question that these read-only tables can be

Well, misunderstandness around. I means making a new table and insert it
into the already opened database *in one step*, or more steps but in an
automated serial and without opening other window and without copy&paste. I
see that the procedure that you described is working and results the same.

I don't know what difference we actually speak about. In my first plan I
intended to use the same paste method and the same "Copy Table" dialog
which is used for "drag'n drop". The difference is in loading of the source
file and so the used csv import UI. But it can confusing too, so it might
be clearer to use the same as in "Connect to an existing database" option.

I will look up these things.

As I see its not an easy hack. In Clalc the import UI is a ModalDialog,
while in Base it is a TabPage which are not a 'mergeable' pair, at least I
don't see the way. Additionally in Base wizard there is no enough space for
all options and for the table which are in the Calc csv import dialog. Plus
the content of the mentioned table (containing expected result) is already
loaded in case of Calc, but in Base file-loading is happen after setting
the csv import options.
If you do that (additionally to the easier Base import UI), you'll
have enhanced not only "import into new base file" but also "connect

I just imagine a 4th option to the start page of Base wizard, with label
"Import table(s) from existing database". For a simple user I think it is
not so obvious that this option can be used to import a table from a
spreadsheet (for example), because by default a spreadsheet not a database
(the same problem i have with "Connect to an existing database" option). Of
course it is good that this option can be used in general, for all
databases but if the user can't see for the first sight that which option
can be used to solve his\her problem than this option not works.

The reason is that I have this task: to add a simple way to import tables
from calc compatible files. :D
But let see how can I use the existent Base wizard and "Connect to an
existing database" option, maybe it can be extended easily.

You have amazing ideas :) But not enough time to implement all of them.
