A clear and concise description of what the problem is. Ex. I'm always frustrated when [...]

When I use two different PC's (ie, my desktop and a conference room PC) changes I make on one (conference room) do not automatically show up on my open copy of the same board on my workstation.

Describe the solution you'd like
A clear and concise description of what you want to happen.

It would be swell if the app was polling for changes frequently in order to render and changes on screen / in the stacks.

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.

Idea 1: Any time something is moved or edits (added / edited / deleted / archived) a 'dirty' value is set in the DB for that board. The web app has a timer that fires every X amount and just looks for the dirty bit. If it is there, it reloads the board. X should be a configurable value with a minimum and maximum value limit.

Idea 2: 'dirty' value may need to be a 'timestamp' app know when it loaded the board. New timestamp means reload. Holding timestamp in memory in browser is not difficult. Would only have to be on currently render board. Same timer rules required.

Additional context
Add any other context or screenshots about the feature request here.

Scenario is not exclusive to me if board is shared and other person can't see updates without switching to another board and back, or reloading the page. Makes it a little tougher on/for collaboration.
