Con Assumes that you always know what you're doing
Buku doesn't show you what will happen before it performs a command that you input. For example: If you type the command to delete a bookmark, there's no way to see which bookmark is tied to the index that you input before the deletion happens. You need to know yourself by checking with another command. Couple this with the lack of a way to undo actions, and you could end up with a situation where you accidentally delete the wrong bookmark (or worse, range of bookmarks) and find out afterwards, without having any way to know which bookmark was deleted by this mistake (because bookmarks are identified by reassignable indices, not URLs or titles) and no way to undo the damage that was done.
This lack of safety means that you must know exactly what you're doing before using dangerous options like "-d", or you could cause irreversible damage.
Con CLI only
Buku's interface is logical, but the lack of a GUI will still be off-putting to someone who prefers them over CLIs.
