Fit to the window option for campaign preview tab

In campaign preview tab there could be some buttons like zoom in, zoom out, fit to the window… because now if the campaign tree is big, you can’t see the whole view of it, you must scroll right and left, up and down…

also, on campaign preview tab inside the boxes I can see what actions will be taken (for ex. adjust contacts point, modify segments, send or schedule email…), but this info can’t be seen in campaign builder. I think it would be nice to see them there too
