views

Allows you to insert a Global PHP field in a view in D7, so you can have conditionals etc.

Note there's a bug in 7.x-1.1 (Jan 2022) - you need this patch.

(Not available in D8, you should use Twig instead).

Provides extra options for aggregating data in tables - e.g. grouping sets of rows together and summing the values of particular fields.

Has a hook - hook_views_aggregation_functions_info() - which lets you add your own options to the table aggregation settings - e.g.  supposing you have a limit for something (number of tickets, nights of accommodation) and want to decrement it - you can write a method to sum the matching rows and then do a calculation on the total.

Also supports 'add column function' - adds a grand total (or other summary field) at the very bottom of the table.

Caution - this module breaks hook_views_pre_render() - you can write your own pre_render method to remove or shuffle entire rows, but any chances to values will be overwritten (discovered this by looking through the source and looking for the use of that hook).  The workaround is to try and do what you need to by using hook_views_aggregation_functions_info() instead.

By default if you add multiple contextual filters to a view, they must all pass (AND).
This gives you a checkbox in Advanced > Query Settings for the view which switches it to OR.

Add extra tables JS support for views (and many other pages) - e.g. search box, dynamic column sorting, rearranging columns, exporting to clipboard etc.

If you get "TypeError: tables.DataTable is not a function" when using datatables module, first, try going to /admin/config/content/table_trash/global_settings and saving the existing settings.

• supports both a 'Load more' button and automated load
• need to turn AJAX on for the view
• patch needed to support back button (adds a preserve history option to settings, which then needs to be turned on)

D7 only (as this is in D8 core as standard).

Converts /admin/people into a fully-fledged configurable view (i.e. fields, filters, exposed filters, header/footer, pagination settings etc.) 

(Dependency: views_bulk_operations)

This module lets you add fields from submissions to view, and sort/filter the view on them, in the same way you would standard fields from the Field API.

It's still alpha and not as polished/robust as the webform module itself - but it's certainly OK to use in production provided you test things first - check every combination of exposed filters works, and double check you aren't seeing duplicate rows (right now I've locked it to a recent commit on the dev-5.x branch, which doesn't need any patches).

Layouts for exposed filters - i.e. you can move each filter into a region (supports Panels and Display Suite).

When I tried this (Summer 2018) the D8 branch wasn't really there yet - you could only rearrange the basic filter components in D8 (like search term, submit button, reset button), not all the extra ones you've added.   I went with using CSS (e.g. clear: both) instead.

For Views that use Table format. Adds a row underneath each record - you change the format from 'table' to the 'secondary row' option, you get an extra select dropdown in the table *settings*, and you can also specify colspan.  This does mean the label will be missing by default (you won't have a column header any more) - so you need to edit the field and tick rewrite output, and then specify your desired label, followed by the field value in Twig.
 

Migrate views from D7 to D8.
Once installed on D7 - you need to go to /admin/config/view-migration 
It outputs multiple YML files and you're specifying a directory to put them in, which you need to create first.

My experience of the YAML output has been:

- incomplete (e.g. multiple missing displays in a complex view, views without a machine name)
- invalid UTF8 due to the next and previous arrows in pager.options.tags being encoded wrong
- the dependencies section at the top of the file not being set out correctly

It doesn't look like there's much current development activity (likewise migrate_views, which is the other plugin people usually mention).
