I maintain a spreadsheet list of smaller tasks that need doing, vaguely inspired by Getting Things Done. Add a priority column and sort. Then each day, review the list to update priorities, and flag items I intend to complete that day. Separate list for major features I intend to add. Works the same as the task list, except on a much slower timescale. That one has ended up being much more valuable. The simple act of collecting this all in one spreadsheet doc has resulted in way more clarity in my thinking and planning. It allows me to bounce between many major areas of work, without losing track. Best of luck!
