    Next SEO

    Next SEO

    Next SEO is a plug in that makes managing your SEO easier in Next.js

    Next SEO is a plugin that makes managing your SEO easier in Next.js projects. Pull requests are very welcome. Also make sure to check out the issues for feature requests if you are looking for inspiration on what to add. Feel like supporting this free plugin? It takes a lot of time to maintain an open source project so any small contribution is greatly appreciated. NextSeo works by including it on pages where you would like SEO attributes to be added. Once included on the page you pass it a configuration object with the page's SEO properties. This can be dynamically generated at a page level or in some cases your API may return an SEO object. Then you need to import NextSeo and add the desired properties. This will render out the tags in the <head> for SEO. At a bare minimum, you should add a title and description. But NextSeo gives you many more options that you can add.

    Notifier for GitHub

    Notifier for GitHub

    Get notified about new GitHub notifications

    Checks for new GitHub notifications every minute and shows the number of notifications you have and shows desktop notifications as well. Displays your GitHub notifications unread count. It checks the GitHub Notifications API every minute. Supports GitHub Enterprise and an option to only show the unread count for issues you're participating in. Make sure to add a token to the Options page. Both requested permissions are optional, so you can just decline if you don't want them. The first time you click on the extension icon, it will ask you for access to browser tabs. We need this to know if there is already an opened GitHub notifications page and switch to it if so. If you want to receive desktop notifications, you can enable them on the extension options page. You will then be asked for the notification's permission.

    One Page Scroll

    One Page Scroll

    Create an Apple-like one page scroller website

    One Page Scroll 1.3.1 by Pete R. Create an Apple-like one page scroll website (iPhone 5S website) with One Page Scroll plugin Created by Pete R., Founder of BucketListly. jQuery 1.9.0 or later is strongly recommended because using jQuery less than 1.8.3 and jquery.onepage-scroll.js together turns out to be a hash-based XSS vulnerabiliry. Modern browsers such as Chrome, Firefox, and Safari on both desktop and smartphones have been tested. Should work fine on IE8 and IE9 as well. One Page Scroll let you transform your website into a one page scroll website that allows users to scroll one page at a time. It is perfect for creating a website in which you want to present something to the viewers. For example, Apple's iPhone 5S website uses the same technique. Now, your website should work the same way Apple's iPhone 5S website does. You should be able to swipe up/down as well, when viewing your website on mobile phones.

    ===NOTICE=== After releasing a few updates, but far less than we wanted, we’ve made the decision to stop the OptimizeGoogle Project. The reasons for the decision were that there were not enough people on the team to keep it going. Google is changing things every day and it has become more and more frustrating to look at all the functions go broke piece by piece. The code will remain GPL, perhaps another person or team is interested in picking this up. For now, thank you for all your patience, feedback and support. Description: OptimizeGoogle is a Firefox extension that enhances Google search results and other pages by adding extra information and removing unwanted information. Created to maintain and improve CustomizeGoogle which seems to have been abandoned.

    OverlayScrollbars

    OverlayScrollbars

    A javascript scrollbar plugin which hides native scrollbars

    A javascript scrollbar plugin that hides native scrollbars, provides custom styleable overlay scrollbars and keeps the native functionality and feeling. The plugin combines the features of native scrolling (e.g. hotkeys, speed, smoothness, touch support etc.) and custom HTML & CSS. It does not replace the native scrollbars, it just hides them to guarantee 100% native scrolling. It also provides additional and highly customizable DOM elements to style your own scrollbars. To check how flexible the styling is, take a look at the examples in the styling demo. Textarea elements have extended support. Dependent on your options, textures can have dynamic width and height. This means the size of the text area is dependent of its content. For more information please read the documentation to the textarea options or check out the textarea demo. No-auto-wrapping (wrap="off") textures are also supported.
