    Startup Helper

    Startup Helper will help you start up the programs you use every day.

    Startup Helper lets users choose which programs are launched when the OS boots up. It also allows for waiting periods between launching programs, to prevent programs slowing each other down. During this startup process, the user can control the waiting period through the Startup Helper GUI, pausing the program, skipping a single program, or foregoing the waiting period and launching the next program immediately. This project is made in Java, so it should be multiplatform. However, I've only been able to test it on a Windows XP machine, so please let me know if there are oddities, bugs and/or malfunctions on other platforms.

    JavaMacros

    A GUI interface written "Around" LuaMacros

    JavaMacros is a GUI "Client" for the LuaMacros "HID-aware" macros program - It runs using Java 8, so you will need it installed on your machine. In simpler words, it is a general way to "reprogram" keyboards in windows, using a graphic user interface rather than directly writing macro scripts, that allows to use any number of keyboards - even of the same make and model - as separate, specific devices. Each with its tailored functions (stickers over the keys are a must). It provides a graphic user interface with a "keystroke recorder" to automatize compiling macros, and support for activating different macros/functions depending on the active window in foreground, whether on its software, class or caption. It also features the ability of defining multiple logical keyboard levels, similarly to how the modifiers on standard keyboards allow to have more than one logical function on each single key.
