I am totally new to Affinity and have been watching a number of tutorials that have been helpful to some degree. My question is, in a number of these tutorials they seem to have a lot more tools / icons down the left hand side tool bar than I have on this latest version / download. Am I missing something to why there are so many more, with seemingly more functions that I current have in version 1.5? Plus I have a picture that is in a portrait format and I would like to try and turn it more into a landscape format without cropping it. How can I do this, or even to squash the photo down so it ends up being more of landscape than portrait. Thanks for your help from a total newbie. :)
