This module is a concatenation of many little things that I like to have and usually would have to create a "mini-module" to get them to work.
The idea is simple: if I wanted to have a Delete tab on my nodes, a second Submit button in my node/edit/* pages, have a text field for the minimum number of words to enter in a node, etc. All those things are very easy to do, but creating a new separate module for each one of them is tedious and uses much more resources on my Drupal installations.
Patch manager provides a developer tool for managing patches to core and contributed modules.
Scary warning
Please think about Patch Manager module as a developer tool that should never be used on production sites. That is so because to apply patches Patch Manager relies on write access to source code of your site by server user. To use this module you need to change default file permissions of files that you want to patch, apply patch and then set permissions back to default. Doing it on production site could lead to security issues - so don't even think about it!
