If I add an attachment to a mail being under composition, well, I can not alter the name of the file. One solution would be to rename it in the file system and attach it again but this is rather uncomfortable.
For example, I use the FireShot extension for Firefox. It would be very easy to send the content of my browser window to an email party:
- click Fireshot icon in the Firefox toolbar (this icon can be configured in a way that it would open the mail composer window with the attached screenshot file)
- define the addresse
- write some words in the email foirm my friend if it is necessary
- “Send”
Fireshot can not find out the file name I want to give the file so it generates a very long and cryptic one. In order to rename it I have to
- save the file
- find it in the file system
- rename
- attach again
It would be much simpler if the context menu of the attached file would contain an item for renaming it. This should not rename the file in the filesystem just send the attachment under the new name.
