Question: Are you planning to change the filesize automatically according to the size of the file?
Ex: If the file is greater than 1024kb the file browser shows 1mb.
exactly!
-----------
1023 b
1,0 k
999,9 k

Regarding the rename feature:
It would be great if you could work on it, as PhyrePhox says, many people has asked for this. The only drawback is that if the filename is changed, Canon's firmware won't be able to recognize it and display the picture, etc.
...
I like it because it is simple but this way you can only rename the files one-at-the-time. I think people soon will ask you for a batch solution.
...
that's why i'm not going to implement batch renaming, there is no point of renaming many JPG files (apart from hiding g-f nude photos

),
it's for some special cases when we really need to change the filename...
EDIT: first i have to do 'any' then will see...
it's quite dirty and hard coded though ...
EDIT:
rename feature is (sometimes)
working, it still needs some polish and bugfixes...
as i found you can't use some letters in the names and all are UPPERCASE,
"|" stands for end of name i.e "FileN.ame|.TXT" will be saved as "FILEN.AME"
usage: LEFT->DOWN->DOWN->DOWN->SET->(LEFT|RIGHT|UP|DOWN)->SET->(LEFT|RIGHT)->SET
here it is if someone wants to try it and fix bugs

there is also filebrowser modification in it (no time to remove).
