We'd like to be able to maintain our Translation Memories by being able to edit and delete entries.

EDIT EXAMPLE. The following Russian translation for the English phrase "Hide Column" mistakenly includes the English phrase itself ...

Скрыть колонку Hide Column

... We'd like to be able to edit the TM here to remove the English words from the end of the Russian translation.

DELETE EXAMPLE. In our Japanese TM, we've mistakenly added the English term "Roll Angle" for Roll Angle! Consequently, we get these suggestions for "Roll Angle", the last one being the rogue English entry that we want to delete from the Japanese TM:

Use 転がり角
Use 回転角
Use Roll Angle
