Key functionality missing.

Hi, could you please tell me if the following features are available for this plugin and if not if it is possible to have them added?
1) unable to deduct an item from a bundle- no X option is available to remove the product completely the only function available is to switch products
2) unable to select Multiple products in a bundle- only one option can be selected.
3) Title for each bundel. only the first bundle has an editable title option.
4) Option for the vendor to check out even if all bundles have not been selected- currently, the only option to proceed to checkout is if an item has been selected in all bundles.

If you could please respond at your earliest convenience much appreciated.
