+<div class="sectionbody">\r
+<div class="paragraph"><p>Many desktop environments nowadays have a way of restarting the applications\r
+that you have been using when you reboot your computer.</p></div>\r
+<div class="paragraph"><p>In i3, we want to take that idea a step further: We want to make it possible\r
+for the user to define a precise layout, which is then filled with the\r
+application windows as they start up.</p></div>\r
+<div class="paragraph"><p>Many users are currently achieving a similar effect with custom scripts and\r
+lots of sleep calls to wait for applications to launch and then simulate\r
+interactive commands to move windows around.</p></div>\r
+<div class="paragraph"><p>Many of the building blocks for this feature are already in place, but there\r
+still are a few places of code that need to be touched, a specification to be\r
+written, user feedback to be gathered and documentation to be updated.</p></div>\r

+<h2 id="_idea_2_testsuite_better_input_and_output">2. Idea 2: Testsuite: better input and output</h2>\r
+<div class="sectionbody">\r
+<div class="paragraph"><p>i3 uses a comprehensive testsuite and cares about test-driven development as\r
+well as regression tests. While our testsuite covers quite a lot of code and\r
+works well and fest, it currently only uses the IPC interface to communicate\r
+with i3.</p></div>\r
+<div class="paragraph"><p>The current state enables us to simulate anything a user might also trigger by\r
+a keypress. This does <strong>not</strong> include dragging windows around, moving the mouse,\r
+clicking on things, or handling actual keyboard events. Furthermore, the\r
+testsuite never sees the actual output the user gets to see. Instead, it just\r
+looks at the data structures.</p></div>\r
+<div class="paragraph"><p>Therefore, it would be good to extend the testsuite so that it captures the X11\r
+output and compares it with saved images. Also, X11 input such as mouse and\r
+keyboard input should be simulated somehow (e.g. captured and replayed).</p></div>\r

+<h2 id="_idea_3_improve_compatibility_with_certain_applications">3. Idea 3: Improve compatibility with certain Applications</h2>\r
+<div class="sectionbody">\r
+<div class="paragraph"><p>We often receive bug reports which are specific to certain toolkits and/or\r
+applications. For example, people are reporting problems with the IntelliJ IDE,\r
+Java applications in general, VMware or Half-Life (via Steam).</p></div>\r
+<div class="paragraph"><p>Most often, these problems are caused by i3 doing things slighty differently\r
+than other window managers and can be solved by observing and comparing what\r
+others do and what i3 does.</p></div>\r
+<div class="paragraph"><p>Fixing compatibility problems is a huge gain for the users of said\r
+applications.</p></div>\r
