This version includes a few bug fixes,
a few features (Merge and Convert tabs now allow for multiple file selection),
and RangeEx.

From README:
What is RangeEx?
A few TextFields around the program expects a valid RangeEx as input, but what is it?

RangeEx, short of Range Expression, is a simple expression system, by me designed, that represents a finite amount of numbers.

RangeEx has 3 basics operations that can be concatenated:
UNDERSCORE ('_')
An underscore represents an interval of numbers, going from the number on the left to the number on the right of the underscore.
Generalizing, an input "X_Y", with X and Y being positive integers and X < Y, will result in all the numbers from X to Y, including Y.
Should always be used between two numbers.

Examples:
"1_4" will result in [1, 2, 3, 4].
"10_15" will result in [10, 11, 12, 13, 14, 15].
"6" or "3" will result in an exception.

PLUS ('+')
A plus represents an addition of the number that follows it.
Generalizing, an input "+X", with X being a positive integer, will result in an interval with only the value X.
Every plus signal should be followed by a valid number.

Examples:
"+1" will result in [1].
"+7" will result in [7].
"+" or "++0" will result in an exception.

MINUS ('-')
A minus represents a subtraction of the number that follows it from a interval.
Generalizing, an input "-X", with X being a positive integer, will result in the current input interval but without X.
Every minus signal should be followed by a valid number.

Example:
"1_4-3" will result in [1, 2, 4].
"5_7-6" will result in [5, 7].

More on Concatenation
One or more spaces (" ") are a valid input to separate things.
This way, "1_3 6_8" will result in [1, 2, 3, 6, 7, 8].
The same result can also be achieved with "1_3+6_8".

Keeping in mind the order of the operations is important:
Every range (underscore) is evaluated first;
Then every addition (plus) is added to the previous interval;
Then every subtraction (minus) is removed from the interval.

Because of this order, are valid unintuitive RangeEx:
"+13 +10", the same as "+13+10", resulting in [10, 13].
"-2 1_3", the same as "-2+1_3", resulting in [1, 3].
"-5 +5 +5 +3", the same as "-5+5+5+3", resulting in [3], since subtraction is the last thing that happens.
"3_7 -4 +20 25_28 +50", the same as "3_7-4+20+25_28+50", resulting in [3, 5, 6, 7, 20, 25, 26, 27, 28, 50].

Because of this, RangeEx allows the user to specifically select pages of a file, even not continuous ones.
