Hi Pete. There are no huge hurdles to implementing this. The following applies to most features that are requested. A lot of features that are requested are generally good (or even great) ideas. If we have enough people request them, or can see that they would be useful and are good ideas, then we will add them to our list of features to implement/design in the future. So, we maintain a list internally that also includes any bug fixes we need to make. This list is prioritised in terms of several factors, for example: bug fixes are generally most important and get moved up the list (there are many other factors also - such as what can be developed within a reasonable release cycle, etc). So - the only "hurdles" to having some features added is that it takes time to make it's way up the list and be developed. This is slightly simplified, as we also have testers that refine designs (or help us decide to remove them).
