-Many tasks remain before calling this version 1.0:
-
-0.0.4
-
-- TStatusBar
-- TEditor
-- TWindow
- - "Smart placement" for new windows
-
-0.0.5: BUG HUNT
-
-- Swing performance is better, triple-buffering appears to have helped.
-
-0.1.0: BETA RELEASE
-
-- TSpinner
-- TComboBox
-- TCalendar
-
-Wishlist features (2.0):
-
-- TTerminal
- - Handle resize events (pass to child process)
-- Screen
- - Allow complex characters in putCharXY() and detect them in putStringXY().
-- Drag and drop

+Jexer Work Log
+==============
+
+March 17, 2017
+
+Jexer is coming back to active development status. I had a lot of
+other projects ahead of it in the queue, mostly Qodem but also Jermit
+and of course lots of actual day job work keeping me too tired for
+afterhours stuff. But here we are now, and I want to get Jexer to its
+1.0.0 release before the end of 2018. After that it will be a
+critical bit of function for IWP and NIB, if I ever get those going.
+I need to re-organize the demo app a bit so that it fits within 80x25,
+and then get to TStatusBar.
+
+A status bar will be an optional part of TWindow. If it exists, then
+it will be drawn last by TApplication and get events routed to it from
+TWindow's event handlers. This will have the nice effect that the
+status bar can change depending on which window is active, without any
+real extra work on TApplication's part.
+
+Putting together a proper TODO now, with release and regression
+checklists. I think I will see if jexer is available at SourceForge,
+and if so grab it. Perhaps I can put together some good Turbo Vision
+resources too. At the very least direct people to the Borland-derived
+C++ releases and Free Vision.
