[TxMt] Bundle opening behaviour

[max]

Hi, 
When a bundle is double-clicked in the finder and there is already one with
that name installed TM displays a dialogue saying:

" The bundle ³<bundle name>² already exists in your Application Support
folder. Do you want to replace it?"

Could there be an option for merging the two bundles? For example, if I
download a bundle that adds extra functionality to an existing bundle, I
don't want to replace or cancel the open action, I want to add the new
stuff. I know I can do it all manually by opening the package but this is
quite time consuming.

The other thing that could be changed in the bundle behaviour is giving an
option of opening it as a scratch project. If I want to do some work on a
bundle's contents, I am not able to drag it onto Textmate's icon because it
tries to install it, rather than making a project.

None of these things are critical, but would be nice to have.

Regards,
Max
