[Qgis-user] SEXTANTE - a few ideas/issues

[johnrobot]

Hi
I have just started trying out SEXTANTE in QGIS and I really like the idea.
A huge step forward and it provides some FME-like capabilities. When working
a bit with SEXTANTE, a few ideas/issues have come up:

1
When trying to run v.buffer (and quite a few other tools as well), I get
this error message:
Ett fel har inträffat vid Pythonexekvering:

Traceback (most recent call last):

    uri = str(layer.source())

When hovering with the mouse over a tool in the toolbox, how about showing a
short explanation on what the tool does?

3
When defining folders, such as the Saga folder, how about using a file
window instead of a blank space for entering the path? This seems easier to
me.

4
A lot of windows, such as the ftools – Centroids, seem to use a lot of space
for no reason. I think that they should be as small as possible.

5
Quite a few buttons, such as the About SEXTANTE – Close, seem much to large.

5
The help button, the ”?”, doesn´t seem to provide any additional
information. Is this planned? Otherwise, I think that it should be removed.

6
I see quite a few abbreviations, such as ”src filename”, ”maxdist”,
”hspacing” and ”patval”. To me, this can be confusing in some cases, and I
think that the full text should be provided. Not sure if this is defined in
the tool and outside of SEXTANTE.

7
When trying to add a tool in the modeller and there is a parameter values
missing, the missing values should be highlighted to guide the user.

8
The user should be able to inspect/edit added components in the modeller,
using for example a double click or a right click.

9
I would like to see some undo/redo functionality in the modeller.

10
Modeller: When shifting between ”Design” and ”Python code”, the view in
”Design” is sometimes shifted.

I use QGIS 1.7.4 and SEXTANTE 1.0.4 on Win Vista 64 bit.

Regards,

Magnus
