expand functionality of app

Hi @smthfrmn, a support question of a moveapps user made me realize that we only have this app to filter by attribute, but no app that filters for the event attributes. I would be awesome if you could expand this App, or create a new one. I think the best way would be to:

• expand the functionality of this App, by allowing to also filter by event attributes. To distinguish by the 2 types of attributes you can use something like this:

if(variab%in%names(mt_track_data(data))){
 # res <- filter_track_data()
} 
if(variab%in%names(data)){
  # res <- filter()
}
if (!variab %in% c(names(mt_track_data(data)),names(data))) {
  logger.error("You selected a field to filter by that is not available in your track attributes data. Go back to the app settings and select a valid field.")
  return(result)
}

You could then rename the App to "Filter by attribute" or create a new one, and deprecate this one. Either way works

• an alternative would be to create a second App "Filter by event data", but given that most users are not aware of the event/track data difference, I think having one App is more intuitive and also easier to maintain.

Let me know what you think, and I'm also happy to help you out.

Thanks! Anne

I think in an ultimate sense probably a shiny app is the way to go, generally I'd like it to have more flexibility for filtering and people could do a combo of complex queries if there were a shiny app. Thanks for the functionality request, I will put it in my backlog!

Shiny Apps are nice, and very useful, but have unfortunately also some disadvantages:

• Currently it is not possible to share the settings of a Shiny App when sharing a workflow. Maybe if the future we will figure this out.
• You have to wait until your workflow gets to your App to adjust the settings and cannot do it before hand. So probably you'll have to run the WF twice for the final result to make sense.
• They are tricky to code, but that of course is just a matter of time investment

Besides all these downsides, there are Apps that have to be shiny and interactive. I think for now having this added feature in a R app will be already awesome. If people want to filter by several attributes they will just have to append the app several times. And than, once a shiny app exists, than we could have a simpler filtering app and a more complex one. Most people will probably only want to filter for 1 or 2 attributes.

But of course feel free to do as you see fit. This is just my opinion based on my experience. Thanks!!
