I'm here to suggest some changes to enhance to today to-do lists.
Today to-do list don't have the option to add sub tasks or make tasks dependent of each other, this would be a big enhance to today to-do list
In dashboard Every task have a line to say from each ticket this task is, why not collapse all tasks below the ticket name? (use less space, more clear)
Ticket Name 1
Ticket name 2
There is not dedicated access to a To-do list feature it's almost hidden in dashboard and you can't rearrange the tasks or sort by priority? (task with priority would be great).
Google to-do list have a details field for each entry so you can add more details about it.
My opinion about the ticket to-do list (time tracking also) menu is that it's hidden below a lot of things, I thin that if you could move it below ticket description it would have a better usage (with more space too)
The side menu, have icons when you click them the page rolls to, but sometime it doesn't, if you grab the idea from google that each menu have it own windows it could enhance not just the to-do list feature but all features will have a great use.
