variable explorer: classify objects

[smortaz]

from user:

The variable browser is very "messy" to navigate - both objects, sourced methods and variables are mixed in one long alphabetical ordered list. You can make this very important window much better.

Place the different types of objects in groups or tabs, like dataset in one group and variables in another. To make it even better, give some quick data at list level. Like with datasets, show if it is a vector, matrix, data.frame, data.tabel etc. That will save the user for calls to the class() function. With variables the data type could be visible etc.

Just some ideas...

I still need this fix for comfortable variable exploration. I tend to make many functions, so my VE is full of functions...

I would prefer to see a column (optional) added to the Variable Explore pane. The current structure allows me to find any object alphabetically, the proposed structure forces me to have knowledge of the object to find it in the explorer. For example, if my data.frame variable is corrupted by a bad assignment I will have to look for it in multiple lists instead of one.

If there were name and class/object type columns, a user should be able to sort the variable explorer by either column.
