[User]
If two or more users exist, you can change the user.
You can also display users other than yourself on the timeline by checking/unchecking the checkbox on the left.
When displaying users other than yourself, this will also be reflected in date lists, pop-ups, graphs, etc.
However, users with a password set cannot display it on the timeline.
[Theme]
You can change the window color scheme by selecting a theme.
There are currently 22 themes available, with the default being Material Graphite.

[Search]
You can search by entering the word you want to search in the search box and pressing the enter key or the start search button.
For details on how to write search words, please refer to About Search.
[Simple calculations]
Apart from search, it also has a simple calculation function.
For example, if you type 2+3 in the search box, 5 will appear on the right side.
Only numerical calculations are possible, string operations are not possible.
Numbers starting with 0x are treated as hexadecimal numbers, numbers starting with 0 or 0o are treated as octal numbers,
and numbers starting with 0b are treated as binary numbers.
Double-click the calculation result to copy it.
In addition to the four arithmetic operations, you can also use the following constants and various functions.
Constants and functions are not case sensitive, and you can even use functions within functions.
