i love the way nebulous Notes implemented acditional keys: you can define macros and Labels for the keys that insert the macro - not limited to single charcters. The macro can be several lines long and can "wrap around" the selction or the cursor position. I would love to have that feature in Textastic
Cursor keys woul be a great improvement (left, right, maybe even word-left and word-right; next/previous paragraph)
if encyption is such a big issue, why not implement plain FTPin the meanwhile?
