A) Sketch Mode
Currently, the comment just takes the image of the situation, but you need to describe in the text of the comment what it is about. The image only gives information about the position but no further context about the issue. I have mentioned the sketch mode in the past, where people can signal with arrows/lines/text/clouds/e.g. what they want to do in the screenshot - similar to the BCF paint action. This sketch mode is necessary to make communication/comments/issues meaningful, as sketching is the most important language of the designer.
B) Paste Image from Clipboard
I mentioned the paste image from clipboard to add alternative graphics to the comments in an easier way. Currently, you need to upload a file with more than a few clicks and keystrokes. Dalux has a good function. If you would allow the paste from clipboard in your comments function it would make the experience exponentially better.
C) Move Indicator
Currently, the indicator of the comment is placed where the last click happened. Sometimes, someone wants to rearrange it to place it better. This does not work. Make the indicator object (plus) movable. Correction: it works with additional shift+left mouse button clicks. Usually, you would expect deselecting. Instead, you move the indicator. Might be good to allow for deselecting and show move arrows at the indicator.
Could also be useful if there was an option to either display the comment as current (“Initials” sign) but only able to see one at a time, you could imagine a view collating all comments or keeping a smaller / simpler display of the comments visible. Sketch below showing the idea,
this would give a global vision of the project and comments easy for design review / technical coordination / client engagement / future development of the project / …
