Feature request: Column numbers when viewing dataframes (View as dataframe feature)

Hi all, 

I was wondering if it would be possible implement a feature in the view as data frame feature. I think this is so useful as I work with data frames with 100's-1000s of columns/rows. I have found the view as dataframe feature incredibly useful! However, what would be really useful would be tto implement something similar to what the 'View()' function achieves in R as follows: 

To see which column.row number you are at. For example, when scrolling mouse over second column, a popup might appear stating '2nd column' or column 2 etc...

and a search bar to search individual elements within the dataframe. 

Is this possible at all? Does it exist within preferences?

Thanks!
