There’s currently no explicit option to configure the widget that way. If you’re experienced with Javascript, you may be able to add the “exclude_replies=true” parameter to the request for the “user timeline.”
There’s a part of the widgets.js file that looks something like:
if (this._isProfileWidget) {
this.url = this._base + ‘&callback=’ + this._cb +
’&include_rts=true’ +
’&count=’ + this.rpp + showSince() + ‘&clientsource=’ + this.source;
}
Which you could change to:
if (this._isProfileWidget) {
this.url = this._base + '&callback=' + this._cb +
'&exclude_replies=true&include_rts=true' +
'&count=' + this.rpp + showSince() + '&clientsource=' + this.source;
}
