questionable button 'delete', critical menu item 'remove', missing menu item 'unversion'

hello,

hopefully this is the right place for thoughts/suggestions regarding the user-friendliness and intuitivity of bazaar explorer.
1. imo in >99% of cases of new existing files/directories, the user wants to add or ignore them. problem is, there are two tiny symbols for that, but left to every new file/directory there appears a delete button. if you are a new to bazaar explorer and in an unconcentrated state of mind, there is a chance to accidentally delete a new file/directory, which is bad :/
is there really a need for the function that new files/directories can be deleted via bazaar explorer?
2. if you right-click on a file/directory in the repo-tree-view and select the menu item remove, there does not appear the question-dialog 'are you absolutely sure?'. if you just want to rename something, but you instead accidentally hit remove, well, definitely something you did not want happened :/
3. i really miss the menu item 'unversion' when right-clicking on a file/directory in the repo-tree-view. i know, it's possible via console or bzr-commands-dialog. but that's not the most convenient possible way.

thx for reply in advance!
