One line logging (with tagging for good measure).
Since 2007, I've maintained a log of things I do at work and in my personal life so I can look back when needed to see when things were done or where I was on a certian day. I've used Treepad for this because it allowed me to quickly hit CTRL-Shift-J to add the date/time and then I'd start typing the information I wanted to log. I've grown tired of keeping TP installed somewhere and having to maintain the data file so I decided to create Mem.Haus to replace TreePad.
It was created by me for me though you're welcome to use it. I'd be happy to hear your feedback on what might make it better.
