Traipse Alpha 'OpenRPG' {091030-00} Traipse is a distribution of OpenRPG that is designed to be easy to setup and go. Traipse also makes it easy for developers to work on code without fear of sacrifice. 'Ornery-Orc' continues the trend of 'Grumpy' and adds fixes to the code. 'Ornery-Orc's main goal is to offer more advanced features and enhance the productivity of the user. Update Summary (Cleaning up for Beta): Adds Bookmarks (Alpha) with cool Smiley Star and Plus Symbol images! Changes made to the map for increased portability. SnowDog has changes planned in Core, though. Added an initial push to the BCG. Not much to see, just shows off how it is re-writing Main code. Fix to remote admin commands Minor fix to texted based server, works in /System/ folder Some Core changes to gametree to correctly disply Pretty Print, thanks David! Fix to Splitter Nodes not being created. Added images to Plugin Control panel for Autostart feature Fix to massive amounts of images loading; from Core fix to gsclient so with_statement imports Added 'boot' command to remote admin Prep work in Pass tool for remote admin rankings and different passwords, ei, Server, Admin, Moderator, etc. Remote Admin Commands more organized, more prep work. Added Confirmation window for sent nodes. Minor changes to allow for portability to an OpenSUSE linux OS (hopefully without breaking) {091028} Made changes to gametree to start working with Element Tree, mostly from Core Minor changes to Map to start working with Element Tree, from Core Preliminary changes to map efficiency, from FlexiRPG Miniatures Layer pop up box allows users to turn off Mini labels, from FlexiRPG Changes to main.py to start working with Element Tree {091029} Changes made to server to start working with Element Tree. Changes made to Meta Server Lib. Prepping test work for a multi meta network page. Minor bug fixed with mini to gametree Zoom Mouse plugin added. {091030} Getting ready for Beta. Server needs debugging so Alpha remains bugged. Plugin UI code cleaned. Auto start works with a graphic, pop-up asks to enable or disable plugin. Update Manager now has a partially working Status Bar. Status Bar captures terminal text, so Merc out put is visible. Manifest.xml file, will be renamed, is now much cleaner. Debug Console has a clear button and a Report Bug button. Prep work for a Term2Win class in Debug Console. Known: Current Alpha fails in Windows.
