It is not an additional comment, but a suggestion, based on the experience gained so far: a feature/app? I consider very useful to use, during SDL-based translation, would be a second screen (apart from the PC/laptop one) to display the target file ONLINE concurrently with the progress of the translation. Why? Often, it would be very convenient to see the REAL format of the text to e.g. choose less characters because of restricted space (specially in case of pdf or Excel or Power Point source text), or change the character size etc., in order to save time required for post-processing of the target translation file.
I suggest to use a second screen because splitting the laptop screen in two halves would be very impracticable because of the available space.
