Questions about S-Base

I have invested an enormous amount of time in making
database applications, using Datapower; but when they
re-designed it for another platform, I stayed with their
last Risc-OS-only version, which I really really like. However,
they no longer support it.

If I change to S-Base, will it do the following things?
(I don't need instructions for doing them - I can read
manuals - but just a fairly simple yes/no on whether
S-Base can be made to answer each of these needs.

1. I need to be able to show a page of records one
below another, 'spread-sheet style' - e.g. to list
the pupils in a class and all their grades, etc.

2. I need to be able to click on an icon which sits
as a field in each record, and thus cause other
software - specifically SwiftJpeg - to do its thing
(e.g. displaying images whole-screen).

3. I am fussy about the appearance of records, and
much prefer to be able to determine in detail their
lay-out, colours, fonts used, etc.

4. It is also important to me to be able to alter this
design at will, without having to start again on
entering the data.

5. I dislike query-formats laid out differently from
the records themselves. Ease of use is much greater,
I find, if the search criteria are entered into something
that is laid out just like a record in that database, and
changes with each re-design of the record.

6. I much prefer Datapower's assumption that you
may want to search on practically any field, and that
they don't need to make you choose a 'key' field. Can
S-Base work like that?

7. As well as formula fields working within a record,
I need some such facility (as I now have) to stick
into a 'header' or 'footer' area something to show
such functions as the sum or average of the values
of a particular field across all records, or all records
turned up by the latest search/query.

I would also like to know the cost of a single-user copy
of S-Base.

Thank you
