My typical use scenario is that I am researching a topic and want to save one or two images per article together with a text summary of that article. I wish to arrange these spatially by pasting images and text into a canvas so that I can get an overview of the topic and recall information by viewing the images.
Back when I ran Windows, I used OneNote
for this purpose since it lets you type text and insert images anywhere, not only linearly. What I did not like was that it organized my notes for me in notebooks. I would like to use my folder hierarchy to sort notes together with other files relevant to each project. I take most short notes in markdown, but for larger notes (e.g. literature review), I like organizing images and text snippets visually on a canvas (preferably endless).
The most suitable software I have found so far are mind mapping programs like xmind
(runs a little sluggish) and freeplane
(got that classic alien java look, but seems quite capable). I would like the software to run locally, rather than being cloud based. Bonus points if it saves files as plain text.
Is there anything more suitable that I have overlooked? Should I keep exploring mindmapping software or is there another category altogether that I am not aware of?
