+    ### Note to self:

+    ### items[page_curr] is the current choice to display

+    ### remember it's a tuple of (caption, action, chosen)

+    ### Python lists are 0-based

+            ### With imagebuttons

+            ### Example: for caption "park", place thumbnail images are:

+            ### "images/place_park_idle.png"

+            ### "images/place_park_hover.png"

+            ### etc.

+    ### Current caption

+    frame:

+        xalign 0.5 yalign 0.8

+        text place_items[page_curr][0]

+    ### To indicate page number

+    frame:

+        xalign 0.5 yalign 0.9

+        text "Current Page: "+str(page_curr +1) # +1 because we like pages starting at 1
