Currently there is a 10 vote per idea cap. It would be nice to be able to allow a user to use all their available votes on one idea. This would allow the user to show that out of all the ideas, a single idea is the most important feature for them. With the 10 votes per idea cap, you may assign the user 100 votes total and if they only really care about 1 idea they can not really show that with only being able to allocate 10 of their votes to the only idea that they care about.
It would be nice to be able to put in a custom number in for the Allocated votes per idea section, instead of being limited to the numbers that are in the drop-down.
