I'd like to treat just a sub-tree, several generations(?) away from the master, as a task list. Everything else may be ideas, information or whatever I collect in my 'mup'.
But when I start updating nodes/tasks in my sub-tree, all the parents up to the top level are updated and changes color as well. I want to inhibit the status propagation from a selected node!

I can do almost everything I want using keyboard. Which is a good thing because I don't have to touch mouse now. The only things left are creating a new map and opening an existing map using a keyboard shortcut.

german "umlaute" (ä ö ü etc.) are replaced by different signs every time you save a map to dropbox. I don't know if the same happens when saving to google drive or other places. Would be nice to have that fixed.

Love the Tab, write, Esc workflow for efficiently building up tree structures. What would perfect this navigation to me would be to support the h,j,k,l keys for navigating like in vim. On my machine I have Esc mapped to Caps Lock in this way I would be able to use mindmup using only the core parts of my keyboard. Might sound crazy but for people used to the vim workflow it makes all the difference. Having to jump to arrow keys for me is a complete disrupt in the workflow.

If it's a big project sometimes we create a lot of Mindmup files. Then if we want a unique Mindmup for the entire project it would be a great feature to integrate all the MindMup files in that new MindMup as new nodes. Here every nodes would be a MindMup files that we could extand with the shortcut "/" .
So the main interest is that in one file we got the entire project !

It would be good to have a subtree attached to the child which gives you contact names of people

Give the chance to not load MindMup with embed images and allowing reference to external locations.

Furthermore, allow to manually edit the URL of external source.

Cloud Based Presentation - enable animation of Mindmup fo presentation purposes - so that ideas can be communicated to an audience through the power of Mindmups!

Possibility to see existing Chrome bookmarks inside a (1 special) Mindmup map (name eg. MindBookmarks) via sidebar (like hotkeys bar) and copy/paste or drag/drop them into node/map.
Sidebar should show present bookmarks folder structure and after placing bookmark in map receive some visual or text sign (or tag) that it is placed in map. Folder/sub hierarchy should be equivalent to parent/children... Also if possible (if Google API allow) to be interactive, ie. if bookmark position (parent) is changed under bookmark folder to be simultaneously changed in map (vice versa).

A smartphone todo list that is syncd to tagged nodes on a mindmup map. I think that is a killer app. Certainly would be for me.
Please...android first if you do it.

If you build a project from this structure, you can need to protect some data from public view.
If you want something from collaborativ user, you need to detect this and make a feedback (ex : to know where users have add ideas, where is the mouse cursor, which nodes have been expand/collapse (or another action), etc.).

I don't know if scripting could be used (or if develop each time something would be best).

Attachment editor not covering all of the nodes.

Ability to edit attachments and nodes at the same time.

Make attachment editor either a floating window on top of nodes or docked under or next to the nodes.

Thanks

Batch commands for subtrees of central nodes & customisable groupings a.k.a select a few nodes and assign them a group number so you can expand or close them faster.

It would be handy to be able to see active links to the last few opened maps. Maybe they could be listed under the controls in the box?
I save everything to Google Drive.
Not sure if this could be implemented given all of the choices you have given us for storage....but it would be handy.

support different shapes like circle, triangle, square ..etc.

Save to a git repository with specifying URI "git://~~~".

I want to save a mindmap to a non-Github git repository. Because Github private repository is not free. Git is not only Github.

With this shortcut, the user simple click on the size of your desire and increase or decrease image size without thinking in pixels
