Well this way is the most-flexible way I think but I would like to see just as in filebox, a special option for edit, used this alot.

Unfortunately did filebox not list all texteditors, like it didn't list txpad or KhtEditor. Nano and leafpad were succesfully integrated there.

Since I compared to filebox, I spotted more convenient differences for example
*Filebox has a nice way to tar a folder and or multiple files
*Filebox has inbuilt ability to open zip and tar internally (maybe even rar too but I don't remember)

Of course this are just request of useful features. You are not forced to implement anything of this. Actually I like the flexibility of putting your own command for open with..

Drawback of this method is that is a bit more unconvienent/difficult to set (for less experienced users).
