Snippet are fine  but there are with latex a lot of commands and it's difficult to remember all the shortcuts and the commands.

Actually, the LaTeX bundle in its current version has almost no snippets. Most things are done with two commands, "Insert environment based on current word..." and "Insert Command based on current words..". These two are pretty customizable and you can add your own environment definitions and stuff. I'm noticing now that the environments "array", "tabular" etc don't have a nice default definition yet, so if someone can suggest what they would want inserted, I can add it to the command.

if i need to open the window of the snippets, i prefer a palette. I think that a palette with tabs for ordering and with the status bar ( the status bar at the bottom of the window is not very esay to use) will be  a extraordinary tool.

I agree, a palette would be very nice. It is just a question of finding someone to write it as a textmate plugin. :) I would if I had the time. Over the summer maybe.

Ah yes, I've seen that. I just thought maybe you knew of something for arrays. What exactly would want for arrays? It would be relatively easy to write a new command that asks you what kind of array you want, and how many rows and columns you want in it, and then set it up. Is that what you are looking for in terms of built in functionality?
