It's been awhile since I've used it. It provides a location field. From what I remember, it's a little buggy. Quote from Mediacurrent, "Address Field - I used to use the Location module fairly often and in early Drupal 7 I used this module. I tend to like the Geofield module a lot more than these particular modules." http://www.mediacurrent.com/blog/top-drupal-7-modules-winter-2014-edition

"Pathologic is an input filter which can correct paths in links and images in your Drupal content in situations which would otherwise cause them to “break;” for example, if the URL of the site changes, or the content was moved to a different server. Pathologic can also solve the problem of missing images and broken links in your site’s RSS feeds."

There are contributed modules that will help with this that are listed below. You can also use Form API's #attributes to add in an HTML5 placeholder. Here's an example using Drupal Form API:

A nice way to add placeholders to input fields. "This module auto-converts form input fields with space-hogging labels into compact mobile-friendly input fields, with placeholders that animate into much smaller labels the moment text is keyed in. "

"Maxlength allows you to set maximum length of any field on any form making use of the form API. This includes fields created using the UI. (Example: any text field on a node)

Open source video solution.

Get autocomplete working for views exposed filters. From the project page: Add autocomplete functionality to the views filter text fields. It works for node titles or cck text fields. The autocomplete results are actually the view results, so they are view related. How to use it: (New) Video Tutorial : http://codekarate.com/daily-dose-of-drupal/drupal-7-views-autocomplete-filter

First off, sorry the title is so long. Anyway, just try this out and you'll see what it does.
