> 1. when composing email message (Email Document) on the SmartAttach window; could you also use the back button as the same function as "Go up" in the Menu list? it's much easier to press a single button to return to the previous window (folder you’re into) rather than pressing more than 1 button
yes, i understand what you mean, but unfortunately the Email message dialog that we use is in fact the one of the Inbox application, it is not a dialog that we have implemented.
and as you know, on smartphone, the BACK key has a different semantic when you are in a dialog that contain text input fields (the BACK key is used to delete characters in text input, and it does not return to the previous window in that case.
However, once you have sent a message, you get back to SmartAttach, and if you want to cancel, select Cancel in the menu (Menu + 7 = two buttons pressed). You can also do Home + OK (Action button).
> is it also limited to pics and tones only?
of course not, you can attach ANY sort of file!
> considering that it’ll surely eats up the IPSM space, how big are the files that can be attached to it?
Not sure, but I think the biggest problem is probably rather the time it will take to send large files, and the cost in data bandwidth. I would recommend to not send files larger than a few 100KB. You can select View > Details in the file selector menu, to see the size of each file.
When you send an email with a file attached, i don't know if a copy of the file is made. probably not. probably it will just read the file at its current location when the mail is sent. to be verified. we don't control that, since the mail is send by the regular Inbox application.
> i’m still trying to evaluate it thoroughly… but so far, it's indeed a great prog!

keep up the good work!
Thanks. Actually it does not do much, really, but we have plans to improve it, e.g. to provide direct access to the folders where common documents are stored (e.g. the photos taken with the phone's camera, etc).
This way you would not have to browse much in the file system!
I figure most casual Smartphone users will not even know what a file system is!
