1. A specifically programmed computing device, comprising: wherein the specifically programmed computing device is associated with a user and is specifically programmed to generate a visually displayed actionable to-do list which is a visual representation of a specifically programmed software container; wherein the specifically programmed software container is being executed by a specifically programmed computing processor; wherein the visually displayed actionable to-do list is caused to be displayed by the specifically programmed computing processor; wherein the specifically programmed software container comprises a plurality of actionable software objects associated with a plurality of native software applications; wherein each actionable software object corresponds to at least one particular software functionality of a particular native software application, at least one particular data object associated with the particular native software application, or both; wherein each native software application is distinct from every other native software application of the plurality of native software applications; wherein the specifically programmed software container is distinctly programmed from each native software application of the plurality of native software applications; wherein the visually displayed actionable to-do list comprises: i) a present actionable area, corresponding to a first time period configured as a present time period, wherein the present actionable area displays a subset of first actionable software objects of the plurality of actionable software objects which have been associated with the present time period based on: 1) at least one first action, being performed by the user, 2) at least one second action, being automatic performed by the specifically programmed computing processor when a future time period becomes the present time period, or 3) both; ii) a future actionable area, corresponding to a second time period configured as the future time period, wherein the future actionable area displays a subset of second actionable software objects of the plurality of actionable software objects which have been associated with the future time period based on at least one third action, being performed by the user; iii) a past actionable area, corresponding to a third time period configured as a past time period, wherein the past actionable area displays a subset of third actionable software objects of the plurality of actionable software objects which have been associated with the past time period based on: 1) at least one fourth action, being performed by the user, 2) at least one fifth action, being automatic performed by the specifically programmed computing processor when the present time period becomes the past time period, or 3) both; wherein, when being executed by the specifically programmed computing processor, the specifically programmed software container is specifically programmed to allow the user to perform, based on a single action, at least the following: i) moving a particular actionable software object of the plurality of actionable software objects from a respective native application to the visually displayed actionable to-do list, ii) moving the particular actionable software object of the plurality of actionable software objects between the present actionable area, the future actionable area, and the past actionable area of the visually displayed actionable to-do list, iii) moving the particular actionable software object of the plurality of actionable software objects within each actionable area of the visually displayed actionable to-do list, iv) specifying at least one of the following: 1) at least one instant action involving the particular actionable software object, 2) at least one future action involving the particular actionable software object, and 3) at least one organizational action involving a visual positioning of the particular actionable software object within a particular actionable area of the visually displayed actionable to-do list; and v) performing a particular activity with the particular actionable software object within the specifically programmed software container represented by the visually displayed actionable to-do list without visually presenting the respective native application to the user.
