Is your feature request related to a problem? Please describe.

There are 3 properties modes possible for the properties window: layer, map and tileset properties

• layer and map properties can only be switched by going to layer and map menu
• tileset properties appear automatically when clicking in the tileset

So if we want to see layer or map properties again, we need to use the menus endlessly. And when clicking in the tileset, the view automatically changes to tileset properties

Describe the solution you'd like

It could be very handy if a button in the properties window is placed to switch between layer/ map/tileset properties. No need to go to the menu. Also in this way the current properties view doesn't change when we click inside the tileset

Start by locating the properties window implementation and the existing layer, map, and tileset property menu actions. Trace how selecting a tileset switches the current view. Done means the properties window offers switching among all three modes and clicking in the tileset no longer changes the view unexpectedly.
