# SaveTab script (Alt-x):
#       - For the current tab:
#         * we do Tab to space (42046)
#         * we do Trim trailing space (42024)
#         * we save the file (41006)
#         * we reload the file from disk (41014)
#       - This script will determine if the tab was already saved or not
#         * if the file was saved previously, we simply save the file
#         * if the file was not saved previously, we create a .txt text file in a given folder
#           (the text file will receive an incrementing number with 2 digits and we fill up any gaps in the numbering that might happen)
#           (see script SaveAllTabs too)
#       - Initially this script was a Notepad++ macro but it lacked some essential functionality.
