If you ever decide to update the app, it'd be wonderful if you added the ability to refresh pages by swiping

If you mean "pull to refresh" then we had it before and it wasn't working very well, if you want to try then you can uncomment the following line in modules/boonex/nexus/template/js.html file:

// $this->_oTemplate->addJs('pulltorefresh.min.js');

and the following block in modules/boonex/nexus/classes/BxNexusModule.php file:

/*
        if ($('.bx-messenger-block-lots').length)
            glBxMobileDisablePullToRefresh = true;
        if ('undefined' === typeof glBxMobileDisablePullToRefresh || false === glBxMobileDisablePullToRefresh) {
            PullToRefresh.init({
                instructionsPullToRefresh: '__txt_pull_to_refresh__',
                instructionsReleaseToRefresh: '__txt_release_to_refresh__',
                instructionsRefreshing: '__txt_refreshing__',
                onRefresh() {
                    window.location.reload();
                },
            });
        }
