I?m writing Ruby scripts for a Raspberry Pi (RPi) using TextMate 
v2.0-beta.1. The RPi is on my network and I?m accessing the files 
via Transmit (OS X FTP GUI program). From Transmit I open, edit and 
save the files. However I just opened the ReadMe.tm created by GitHub, 
did some editing, saved and closed. I hadn?t seen that I had 
received a notice from Transmit that I didn?t have permissions to 
modify the file, but the changes were gone (RPi is slow).

TextMate tells Transmit that the file has closed, it does not remove it 
(this would be done by Transmit). It also does not know, that Transmit 
is unable to upload the file.

So I don?t think TextMate can really do anything better here.
