So you’ve written some WordPress plugins and now you want to let your readers know about them?
The WP Download Counts plugin lets you do just that. It adds a sidebar widget which retrieves a list of your plugins and displays them along with the current download count (updated every 15 mins) and a link to each plugin’s listing in the WordPress Plugin Directory.
Features include:
<ul>
<li>Minimal configuration required – just a title and your WordPress username </li>
<li>Plugins listed in order of the most-downloaded first.</li>
<li>Plugin information cached for 15 minutes to minimize overhead</li>
</ul>

Very simple, highly customizable counter widget for showing difference in 
days from a specified date and time. Allows HTML in title and body. Can 
count up and down. Supports multiple instances.
Originally developed as a baby age counter, but can be used for any counting 
job.
The options in the widget are:
<ul>
<li>
Title is the widget’s title. It can contain HTML; its value is simply embedded into the resulting HTML page.
</li>
<li>
Content is the widget content field. It uses the <a href="http://www.php.net/manual/en/dateinterval.format.php" rel="nofollow ugc">DateInterval::format</a> 
function to format the field contents. You can use any field specifiers from 
that function. Its contents are also embedded into the resulting HTML page, 
so over the %-tags, you are free to use any HTML you want.
</li>
<li>
Date specifies the date we should count difference from. Since this 
plugin simply calculates the difference between ‘now’ and the specified date 
(in 24-hour days), it can be used for counting down, for dates in the 
future, or counting up, for dates in the past.
</li>
</ul>
You can have multiple instances of this widget, of course.
For an example usage, see the screenshots section.
