Should Turn Order values be just integers?

Currently players can enter text which screws up the sorting. Shouldn't this be a numbers-only field?

Players can also delete their tokens, spam chat, quit mid-session, or verbally abuse everyone through the microphone. If they refuse to roll initiative with the provided button, don't let them act in combat... or just boot them and find players who aren't idiots. Having the option to use text in the turn tracker could be quite useful to some people.

A lot of systems also use the decimal tie breaker approach too, so pure integers wouldn't be a popular decision. There are also systems that use playing cards for initiative... it's all about being system agnostic from a Roll20 design perspective. But you are right, players can do annoying things which is why the DM has the power to request that they stop and ultimately remove them from the game should they fail to comply with polite and reasonable requests :)

The tracker is the only place you can store and interact with variables without API. There are some tricks which take advantage of this.  The value in the field is only used for sorting when you click the sort button. After that you can use it for anything without changing the order. You can for instance use a macro to decrease the value by 0.1 for each charge on a wand or staff. It wont change the order but give an indication of the number of charges used. After sorting you could set the value to the number of arrows available and decrease it by one every time one is fired. I believe you can also include text for external links.

Oh. If you sort by number and they put text in then they should be at the bottom of the list. Serves then right going last if they can't be bothered to press the correct button.
