Hi there :)
Thanks for flying with me and just read this once to be sure you know everything about me...

Just enter the thing you've just done to the input field at the top right and press enter to add it to the list. The start time will be the startup of this site or the end of the last entry if you added something. (If you just press enter without entering any text no entry is created but the start time is set to now - usefull for example when you return from lunch.)

If you close the browser just don't fear, your data is stored in HTML5 database of your browser so as long as you don't change the browser your data stays with you. To remove an entry do a double click on it and it will disappear. Clicking one time will copy the topic of it to the topic field.

Hope you understood everything and now have fun :)
