There is an old add-on for 2.2, http://addons.oscommerce.com/info/1230 , it could be upgraded to work with BS

You could use this as a starting point in making your own module: http://addons.oscommerce.com/info/6917

1. Set Force Cookies to true. (osCsid in url not used, users with browsers that does not support cookies will not be able to buy from your shop) Or 2. keep it as you have it but make sure that Prevent Spider Sessions is set to true. (makes it so bots does not get osCsid)

Moving to a more dynamic fields model could be a way to go, this would allow the option to create extra fields/labels in admin that would automatically be used in all the required instances.

If it works on PHP5.4, it should not be that much work making it work on PHP5.6.

You can not edit/remove add-ons, you can only add in new packages. The old entries and files remain available for download as an archive for those who wish to checkout old versions. If there are major changes you might instead want to add it as a separate new add-on. If you have other needs and can not get hold of the site webmaster, you might try contacting one of the moderators and ask about information/assistance.

A final version of V2 should be released, responsive with bootstrap and then that should mark the end of life for v2. (possibly with some running bug fixes and php/MySQL compatibility patches) Then all resources should rather be focused on a brand new V3, using a modern modular codebase and structure. (should ofcourse also among other have a template system)

The "upcoming" OSC V2.4 have a neat auto "prefix" functionality which works just fine with hard coded table names.

you have to add in the scripts from bxslider , eighter in template top or make a header module. as well as editing the product info page to use bxslider for the images

change to

Opencart 2+ has an interesting system in place for core modification, its called ocmod. (and/or and extension called vqmod) In short what it does is make a copy of the core files where modifications are done according to an xml instruction file, then the copy file will be used instead of the core file. This makes adding extensions and updating the core fast and easy. Its not perfect, has restrictions and conflicts do happen, but its still an interesting way of doing things and might give some food for thought.

there should be a hook command for adding stylesheets and js file links to the head section, that would be the preferred way. That would also allow for "auto" minifying and combining scripts/css.

Dark Background Oscommerce 2.3.3.4 Template V1.2 What's changed in V1.2? - Misc. checkout color changes. http://addons.oscommerce.com/info/8990

For multi currency shops...yes

My suggestion would be to make an official V 2.3.5 , where the only major change from 2.3.4 is that jquey ui is replaced by Bootstrap 3 to make it mobile responsive. This would give oscommerce responsive design in the current official stable version right now and then the development of the new 2.4 could proceed at its own pace.
