A little suggestion: option to flag "table with no headers" (or nonstandard headers, undetectable by TableTools) to sort/filter since the first row.Example with "error" (first row treated as a header):

I'm Brazilian, and pt-BR of this extension confused me.
"Sort/Filter Row starts from clicked row" was translated as "Sort/filter only rows below" ("Restringir ordenação/filtro às linhas abaixo"), should be "Ordenar/filtrar a partir desta linha".
Similarly, menuitem.sort.up.only should be "Ordenar/filtrar até esta linha".

There is actually already a way of dealing with this: Right click in the first row of the table, choose TableTools2->Other->"Sort/Filter Row starts from clicked row". This will allow you to sort the entire table (albeit due to the lack of a proper first row to detect sorting direction, you have to click twice to sort again in a different direction).

My old TableTools addon had the option to allow table with no headers, but in TT2 I thought, why not allow user to set it on-the-fly for specific tables instead of going to Options to change it for all tables? Hence the context menu item.
