# Blessed v0.1.0 - new terminal goodies for node.js
![blessed](https://raw.githubusercontent.com/chjj/blessed/master/img/v0.1.0.gif)
## New useful options for your typewriter application:
- __`dockBorders` option__ - Element borders will automatically "dock" to each other. Instead of overlapping the borders end up connecting.
- __`autoPadding` default__ - Auto padding is now enabled by default, meaning blessed will automatically position elements inside their parent's border.
- __`rleft` property__ - Relative offsets are now default element properties (`left` instead of `rleft`).
- __`draggable` property__ - Make any element draggable with the mouse.
- __`Table` and `ListTable` elements__ - Tables with a high quality rendering.
- __`Log` element__ - A top to bottom logger box with scrollback and other features.
- __Obscurable borders__ - In addition to docking borders, it's possible to obscure borders by sliding them off the screen with negative offsets.
- __Percentage expressions__ - Like CSS, arithmetic can now be performed on percentages. e.g. `width: '50%-1'`. This is useful for overlapping borders on elements with a percentage width.
- __`shadow` option__ - Give the element a translucent shadow. Automatically darkens the background behind it.
- __`transparent` option__ - Lower element opacity to 50%. This will display dimmed elements and content behind the foreground element using a naive color blending function (good enough for a terminal's limited amount of colors). works best with 256color terminals.
## Other features that weren't mentioned before:
- __`setHover` option__ - Set a hover text box to follow cursor on mouseover, similar to how a web browser handles the "title" attribute.
- __`Terminal` element__ - Spin up a pseudo terminal as a blessed element. useful for writing a terminal multiplexer. (requires term.js and pty.js as optional dependencies).
- __`Image` element__ - Uses `w3mimgdisplay` to draw real images your terminal. this is much easier than calling w3mimgdisplay by hand. Image elements behave like any other element, although it is wise to use `width: 'shrink', height: 'shrink'`.
---
The major things that justified the 0.1.0 release were fixes and stabilization of api (`autoPadding`/`rleft`/`left`). Scrolling boxes were almost completely revamped to work a bit smarter.
---
## Things yet to come:
- __@secrettriangle's [improvements](https://github.com/slap-editor/slap) for textareas__ - This allows for real text navigation.
- __Gravity and margin layouts__
This is something that's been in the idea bin for a while. Every element could
potentially have properties like:
```
gravity: 'bottomleft',
margin: 5,
``
In other words, just a more complex `float` system than what the CSSOM is used
to.
