← IDEAS? What Should We Do Next?

I suggest you ...

You've used all your votes and won't be able to post a new idea, but you can still search and comment on existing ideas.

There are two ways to get more votes:

  • When an admin closes an idea you've voted on, you'll get your votes back from that idea.
  • You can remove your votes from an open idea you support.
  • To see ideas you have already voted on, select the "My feedback" filter and select "My open ideas".
(thinking…)

Enter your idea and we'll search to see if someone has already suggested it.

If a similar idea already exists, you can support and comment on it.

If it doesn't exist, you can post your idea so others can support it.

Enter your idea and we'll search to see if someone has already suggested it.

  2. Select All

    Selecting Multiple file is a hassle, if I want to upload/move/delete multiple files at once I have to select them one by one which is not productive.

    I suggest "Select all" button and cursor selection feature.

  7. I suggest you require prerequisites before allowing anybody to enroll in this program

    Taking the data science classes by anybody unfamiliar with any of the basic programs used during this course makes no sense. It's monumentally frustrating trying to figure out the basics like this:
    Exercise 3: (Jupyter notebook)
    2. From the menu, click on "Insert", then "Insert Cell Above" or "Insert Cell Below".; While it's clear how to insure one or the cells, it's difficult to figure out how to enter the second now.
    3. Note you can use the keyboard shortcuts: [a] - Insert a Cell Above; [b] - Insert a Cell Below. Really? What am I suppose to click on??????

  8. Not always so clear on when I have a correct answer

    Your user interface doesn't always make it clear that I am correct. Also adding print(xxxxx) to the answer when you're asking for output shouldn't be counted as wrong.

  15. correct grammar on ML0120EN-1.1-Review-TensorFlow-Hello-World.ipynb

    ML0120EN-1.1-Review-TensorFlow-Hello-World.ipynb

    After block 4, it says "it's" in a place where it should say "its", because it is a possesive, not a contraction of "it is".

  18. My Courses section should be divided in Completed and In Progress.

    Additionally, a progress bar would be nice to have and a feature to resume learning from where you left off.
