You are right, and also that seems pretty easy to do (but I will need some time
to do it because I am currently packaging Scid for Pocket, and I am discovering
a new world...).
Another suggestion you may find useful : I added a book window, so if you really
have a favorite reference DB, why not generate a book with polyglot from it so
you will get a very quick navigation (no calculation when moving). Moreover you
can edit on the fly the book : for example even if the reference DB shows 4
possible good moves, your personnal way of playing may make you avoid one of the
moves : you then just put a 0 in front of it. So you get at the same time a
reference for ideas, that is fast, and that you can also edit ...

I  already looked at that and it is not completely straightforward to code
(Trees use an unique filter, that needs work to support multiple trees). But
when I added the book window feature, I thought that would make useless the need
for multiple trees, don't you think ?
Currently you can have :
- a Tree opened and locked to a reference base;
- a working base opened ;
- a book opened in read only mode ;
- a book opened and editable ;
Isn't it sufficient ? (at least for my chess skills, it is !). See my previous
answer : isn't it preferable to go through books instead of bases ?

Tree is slow : Yes ! this is where the books come into action : fast,
lightweight and efficient !

Ok, I added a button in engine window to start/stop analysis for exactly the
same reasons you explain here for tree window : so I will do it (but again,
believe me, Scid in your hand on a Pocket PC is so nice, that I have first to
stop playing with it to get spare time).
