TxtEdit 1.4.1 questions

1. "Fixed Rows" and "Fixed Cols" tooltips are swapped.
2. One cannot adjust length of fixed column.
3. [FR] Could there be an option to fill column (selected cells? starting from the cell?) with [auto-incrementing] indexes?
4. Is it possible (and does it worth it) to make TxtEdit remember fixed cols/rows count for ~~custom TxtTables~~ previously opened files?
