+Ultimately boils down to getting `height` and `width` for:
+- prompt
+- preview
+- results
+
+No matter what you do, I will not make prompt have more than one line (atm)
+
+Result of `resolve` should be a table with:
+
+{
+  preview = {
+    get_width = function(self, max_columns, max_lines) end
+    get_height = function(self, max_columns, max_lines) end
+  },
+
+  result = {
+    get_width = function(self, max_columns, max_lines) end
+    get_height = function(self, max_columns, max_lines) end
+  },
+
+  prompt = {
+    get_width = function(self, max_columns, max_lines) return 1end
+    get_height = function(self, max_columns, max_lines) end
+  },
