I would like that the Browser data, start loading in the gui only a chunk
of the whole dataset, like the first 250 rows, and then automatically
loads another chunk of rows when I'm close to the bottom.

You can see an example of what I mean if you open the sqlite database
using sqliteman [0].

Do you think that would be feasible do the same thing with the wx?

Large datasets can be quite slow to load...

I too run quite often in problems with large data sets. The solution
suggested above would be great. An alternative could be to load X rows and
have 'next' page button to load the next X rows (in such case it would be
good to offer the extra option, through a check box perhaps, to load all
data in once and to have the option to set the number of rows to load in
each page).
