ImGui was also designed to function with touch inputs if you increase the padding of widgets to compensate for the lack of precision of touch devices, but it is recommended you use a mouse to allow optimising for screen real-estate.
+I recommend using [Synergy](http://synergy-project.org). With the uSynergy.c micro client running on your platform and connecting to your PC, you can seamlessly use your PC input devices from a video game console or a tablet. ImGui allows to increase the hit box of widgets (via the _TouchPadding_ setting) to accomodate a little for the lack of precision of touch inputs, but it is recommended you use a mouse to allow optimising for screen real-estate.
