[Discover] Copy rows as text to clipboard UX / UI enhancements

[renshuki]

Tested on:
- Kibana 8.11.3 and 8.12.2
- Chrome Version 123.0.6312.59 (Official Build) (arm64)

Describe the feature

The behavior of Discover - Document Explorer compared to the Discover - Classic View (legacy) differ when it comes to copy content.

Extracting content via mouse select / copy

• Extracting content (rows) from Document Explorer is currently difficult. As you can see below, mouse selection of the rows is not always working as expected.

In this example, the first line and second-last line are not selected

• Copy-pasting the content to a text editor is rendered as:

Being able to keep the "row" format would be nice.

Copy documents to clipboard as TXT

• When selecting rows using checkboxes, only a Copy documents to clipboard (JSON) option is available. I suggest adding a Copy documents to clipboard (TXT) option as well.

Example:

The Copy documents to clipboard (TXT) would copy the rows as displayed in Discover.

Select all checkboxes feature

• Checkboxes can be selected one by one but there is no feature to select all rows (as I'm aware of).

Example:

Shift+click to select multiple rows

• Capability to do a shift+click to select a specific range of rows

Describe a specific use case for the feature

CSV Reports feature could be used to extract content from Discover but:

• it takes time to generate
• the CSV file should be downloaded locally
• the CSV file should be opened in a dedicated app (i.e. text editor)

Please consider above enhancements for a more seamless method to copy Discover content to clipboard.

thx for the input and the detailed description, this will be a useful feature. Adding a note by @davismcphee who recently a document comparison mode to the table (#166577), that we might consider capping the number of comparison docs.

Thanks @kertal, I just noticed I uploaded the wrong screenshot for the Copy documents to clipboard (TXT) part, now edited and I hope it makes things clearer :)
