A portable cross-platform sticky note application.
...It is very simple and its use recalls that of the real sticky notes in the following three steps:
1. create a new / take a note;
2. (re)edit it;
3. stick it.
YSticky is developed in Java so needs the Java Virtual Machine (version 6 or higher) that, in the case, is very easy to download and install. It does not need installation since quickly creates and edits notes in the same directory of the executable.
