Make it possible to open files natively in a single action and expand the key bindings
One of the things I dislike the most about TagSpaces currently is that in order to view a file that isn't supported by the internal file viewer (and quite a file formats are not supported right now), you have either open the 'File Operations' menu and select 'Open File Natively' or open a preview of the document and then select 'Open File Natively'. I think you should be able to make a key binding for 'Open File Natively' as you are currently able to do with a variety of other functions in TagSpaces. In fact, now that I think about it, every function in the 'File Operations' menu should be able to be assigned a key binding, including 'Move or Copy file', 'Delete File' and 'Rename File'. I'm of the opinion that optimally, a task should be able to completed with the fewest number of actions possible and increasing the number of functions able to be bound to key bindings would help address that.
