It's as I expected .. you have to modify a core control. Would this give me problems in the future with hotfixes etc ?
Then why not create your own module and copy this exisiting module so you can make customizations to it. It is way more flexible than you expect, just have to be willing to take the leap to do it. Just because its a small modification to a core control doesn't mean it can't be done or that future hotfixes won't be applied.
Submit your suggestions on http://kentico.uservoice.com if you thing they should be part of the core. You have to ask yourself, how many times have you needed this functionality for different clients? If you use it all the time, create your own but if not, then why would Kentico want to weigh down the product with useless items that may or may not be used.
