PyMS v1.2.0 has been released. Some highlights from the changes are:
General: -Totally revamped MPQ and settings handling. This also means no PyMS program should ever hog your MPQ's anymore
-On Windows all resizeable programs now save their maximized state between uses
PyAI: -PyAI now keeps track of your aiscript.bin and bwscript.bin's file sizes and displays them in the statusbar
-The Script Editor now shows at most 5 of the script ID's (that were selected when it was opened) in its title
PyGRP: -You can now select multiple bmp's to import instead of being stuck with the "same name" mechanic (which PyGRP uses for the command line bmp to grp conversions)
-Added a "Transparent Index" option (like SFGrpConv) to choose which index in the palette will be used for transparency (can only be changed when a GRP is not open)
-You no longer need to specify if you are loading an uncompressed grp, only if you are saving to one
PyICE: -The IScript Editor now shows at most 5 of the script ID's (that were selected when it was opened) in its title
-The IScript Entries list now only shows entries that are actually in the file
-Added support for custom IScript ID's greater then the default iscript.bin's highest ID
-Added a new special header extension (like the GRP frames extension from v1.5) to define a custom name for IScript entries
PyLO: -Updated the previewer, now it is located in the main window, can preview GRP's, and allows drag and drop for changing offsets
PyTBL: -Added a text previewer
-Added the color list to the main window and removed the colors window
PyTILE: -Added tile Group, MegaTile, and MiniTile Importing/Exporting to the Tile Palette window
As well as lots of bug fixes. I highly recommend updating!
