I am kinda beta-testing Tabup myself, before opting to extend invites to new potential users in two Tabup groups I am assembling [one is a Cub Scout Pack, the other is a Boy Scout troop].

I am noticing that several dialog boxes have the choice selection boxes in reverse of the intuitive order that the rest of software world has agreed upon.

The two most striking examples are:

Placing "No" to the left of "Yes"
Placing "Cancel" to the left of "Save"

The consensus of dialog box layout in the software world is "Yes" followed by "No"  , and "Save" followed by "Cancel"   [reading left to right]

This reverse ordering is confusing.  In a few days of building my test Tabup group, I have accidentally hit the wrong selection several times, plus many near misses.  

Please correct the ordering of your choice selections in your dialog box layouts, to conform to commonly agreed layouts.
