 # iOS example
 
-----
 ## Introduction
 
 This example is the default XCode "OpenGL" example code, modified to support ImGui and [Synergy](http://synergy-project.org/). 
 
+It is a rather complex example because of all of the faff required to get an XCode/iOS application running. Refer to the regular OpenGL examples if you want to learn about integrating ImGui.
+
 Synergy (remote keyboard/mouse) is not required, but it's pretty hard to use ImGui without it. Synergy includes a "uSynergy" library that allows embedding a synergy client, this is what is used here. ImGui supports "TouchPadding", and this is enabled when Synergy is not active.
 
 ## How to Use
-----
 
 0. In Synergy, go to Preferences, and uncheck "Use SSL encryption"
 0. Run the example app.
@@ -16,7 +16,6 @@
 0. Enter the name or the IP of your synergy host
 0. If you had previously connected to a server, you may need to kill and re-start the app.

 ## Notes and TODOs

 ## C++ on iOS
 ImGui is a c++ library. If you want to include it directly, rename your Obj-C file to have the ".mm" extension.

- - window: add a way for very transient windows (non-saved, temporary overlay over hundreds of objects) to "clean" up from the global window list.

  - window: allow resizing of child windows (possibly given min/max for each axis?)
  - window: background options for child windows, border option (disable rounding)
+ - window: add a way to clear an existing window instead of appending (e.g. for tooltip override using a consistent api rather than the deferred tooltip)
  - window: resizing from any sides? + mouse cursor directives for app.
+!- window: begin with *p_opened == false should return false.
  - window: get size/pos helpers given names (see discussion in #249)
  - window: a collapsed window can be stuck behind the main menu bar?
+ - window: detect extra End() call that pop the "Debug" window out and assert at call site instead of later.
 !- scrolling: allow immediately effective change of scroll if we haven't appended items yet
+ - splitter: formalize the splitter idiom into an official api (we want to handle n-way split)
  - widgets: display mode: widget-label, label-widget (aligned on column or using fixed size), label-newline-tab-widget etc.
