[ferret_users] General question about functionalities and customization

["'Fabio' via _OAR PMEL Ferret Users" <ferret_users@xxxxxxxx>]

Dear all, I’m sorry for the multiple questions but I thought it was 
better than just sending multiple emails. I’ve searched up and down the 
manual and the Internet but cannot find answers to the following questions.

1.	How do I reload the files when they have changed? At the moment I am 
using cancel data/all and then have to “use file1.nc”, etc.
2.	Is there autocomplete variable names, commands, palette names, etc. 
similarly to R console or linux Bash?
3.	Can I only access one data set at the time? Or is it possible to do 
something like: plot variable/data1, variable/data2? If not, is it 
possible to quickly merge two data sets with the same time steps and 
spatial extent inside ferret?
4.	Couple of questions in regards to the command history files. How do I 
use them? Because when I type “go ferret.jnl” I get this message 
**ERROR: ferret.jnl: Success. And is there a way to disable them? They 
tend to fill up my folders with lots of history files.
5.	Is there any way to control the size and position of the plot window 
when the first plot command is used? I use ferret through Xterm and 
always have to reposition and resize the plot window when I open a new 
instance of ferret.

Thanks in advance for any help or feedback!
